Abstract :
Due to the large number and strong randomness of EVs (electric vehicles), their participation in the peak adjustment demand response of the grid through V2G aggregators is highly uncertain, which not only affects the operation quality of the grid, but also cannot guarantee the economic benefits of aggregators and users. Therefore, an effective response mechanism is urgently needed to guide EV to reasonably participate in the grid service. In consideration of the profitability requirements and development prospects for V2G aggregation businesses, we propose a multi-temporal optimization scheduling strategy that takes into account the reliability of EV peak demand response.Firstly, the day-ahead pre-scheduling of EV demand response is carried out with the goal of optimal integrity-capacity comprehensive index of EV cluster. Secondly, in order to cope with the adverse impact of intra-day EV default uncertainty on peak demand response, the V2G aggregator uses the intra-day default emergency mechanism to conduct emergency response invitation for the whole range of EVs, and then optimizes EV scheduling with the dynamic evaluation model with the optimal response reliability index. Then, the benefits related to peak regulation demand response are evaluated by V2G aggregators and on EVs sides, including the demand response benefits and default costs of the power grid and aggregators, as well as aggregators and EVs. In addition, the surplus of the default capital pool of V2G aggregators is issued to EV with good credit in the form of credit incentives to encourage EV to keep its promise. Finally, a simulation example is used to verify that the proposed optimal scheduling strategy for peak demand response can effectively improve the reliability of EV cluster response and increase the effectiveness of economic benefits for EV and V2G aggregators. © 2025 Science Press.

Abstract :
An operating model for nuclear-hydrogen integration (NHI) is developed based on an in-depth analysis of the future trajectories of the electricity and hydrogen markets. A planning model is proposed to determine the optimal capacity allocation ratio between nuclear power and hydrogen storage systems, while also optimizing the on-grid output of NHI within a reasonable range of system load factors. The results indicate that the optimal capacity ratio of nuclear power to electrolyzers and fuel cells is approximately 1: 0.41: 0.36. Flexibility analysis shows that NHI adjusts output from 51.3 % to 128 % of the rated power for nuclear power, enabling it to adapt effectively to load variations. Economically, NHI achieves a total revenue of 18.37 billion CNY, which is approximately 56.0 % lower than that of nuclear-pumped storage integration (NPSI). These findings suggest in regions with favorable geographical conditions for constructing pumped storage power plants, NPSI may represent a more economically viable operating strategy.

Abstract :
In order to solve the problem that the optimal decision obtained by the traditional reactive power optimization model is difficult to adapt to the voltage over-limit caused by the ultra-short-term forecast deviation of wind power in the actual scheduling, a reactive power adjustment strategy for loss reduction considering the ultra-short-term forecast deviation of offshore wind power is proposed. The probability density function of voltage deviation is obtained based on Gaussian mixture model and linearized power flow equa-tion in order to evaluate the nodes with the risk of voltage over-limit and the voltage fluctuation ränge under the forecast deviation of active power Output. Based on this, combined with the influence mechanism of the forecast deviation of active power Output on voltage, an optimization model of reactive power adjustment for loss reduction is established to reduce the reactive power optimization ränge of the corresponding wind turbines based on the maximum voltage deviation of the risk node under the influence factor of a certain risk node, so as to improve the safety and economy of the reactive power adjustment strategy for loss reduction. A real 91-bus offshore wind farm is taken as a Simulation example to verify that the proposed method can avoid high voltage over-limit penalty costs to the maximum extent, and obtain high loss reduction benefits by reactive power adjustment. © 2025 Electric Power Automation Equipment Press.

Abstract :
In order to adapt the network structure of a distribution network to the access of new energy technologies such as distributed generation (DG), energy storage and DC loads, a new network planning method for AC/DC hybrid distribution networks is proposed. The method considered all possibilities of the AC/DC configuration to improve the economic benefits of the network construction, and constructed a linearized single-layer network planning model to improve the global optimization capability in view of the difficulty of obtaining global optimal solutions for the network planning model. Firstly, considering that AC/DC types of buses and the connection states between buses determine the investment cost of converters and lines, which determines the economic benefits of distribution network planning, a binary bus type matrix is used to represent AC/DC types of buses, a binary network association matrix is developed to represent the connection states between buses, and binary line type variables are adopoted to represent line type selection to construct network structure decision variables, achieving a description of the overall network structure. Secondly, with an objective of converter installation cost, line construction cost and system operation and maintenance cost, a single-layer network planning model is established considering elaborated and practical constraints, such as the number of node-connected lines, line selection constraint, power flow, voltage source converter (VSC) reactive power compensation capacity, system safety operation, energy storage operation, network connectivity and so on. In this proposed model, the AC and DC current models is unified by introducing branch type variables, thus linking the planning layer and operation layer, so that network planning variables and operation optimization variables consisting of power purchased from the distribution network to the grid, DG output, energy storage charging and discharging power and VSC power were optimized simultaneously to enhance the possibility of obtaining a global optimal solution. Finally, to achieve better sulution, power flow equations and line transmission capacity constraints are linearized by a series of linearization methods, such that the mixed integer nonlinear programming (MINLP) problem was transformed into a mixed integer linear programming (MILP) problem, and the GUROBI solver is invoked in Matlab to solve it. The validity of the planning method was verified in a 13-node distribution system. The simulation results show that: (1) The AC/DC hybrid distribution network planning scheme can save 5.05% of the total investment and operation cost compared with the pure AC distribution network planning, and the network structure of the planned AC/DC hybrid distribution network also has greater network supply capacity, which illustrates that the AC/DC hybrid distribution network is more advantageous in the case of mixed AC/DC sources and loads. (2) The proposed planning method saves 13.54% of the total investment and operation cost and 91.32% of the computation time compared with the traditional bi-layer planning model solved by genetic algorithm, which indicates that the single-layer network planning method has prominent global optimization performance and faster computational efficiency. (3) As the method does not require relaxation of constraints, compared to second-order cone planning techniques, there are no limitations in terms of grid topology, etc, and it is suitable for the planning of both radial and meshed distribution networks. © 2024 China Machine Press.

Abstract :
To effectively address the issues of low utilization and challenging cost recovery in distributed energy storage, it is crucial to study trading mechanisms tailored to distributed energy storage. The business model of the sharing economy applied to the energy storage field has potential, and many existing methods have implemented diverse energy sharing transactions using blockchain technology. However, these studies have not adequately considered the convenience of energy storage operations. To tackle this problem, this paper views energy storage as a physical device and designs a more user-friendly coupled charging and discharging sharing mechanism. This approach reduces transaction risks while enhancing the control rights of energy storage participants. First, a business model for energy storage sharing was explored, and a sharing mechanism that separates ownership and usage rights was studied. The trading process, application scenarios, pricing mechanisms, credit management, settlement mechanisms, and rolling trading models supported by blockchain technology were investigated. An optimization model for energy storage sharing that couples charging and discharging rights was established. Then, a decentralized and privacy-focused blockchain platform was built. Smart contracts were used to facilitate the transfer of energy usage rights and control of charging and discharging. This platform ensures the sustainability of energy storage systems while highlighting their role as leaseable physical assets. By simulating scenarios where distributed energy sources and electricity consumers participate in energy storage sharing for deviation handling, we assess the feasibility of the energy storage sharing market. From the perspective of energy storage, profitability depends on initial investment and maintenance costs, as well as equipment parameters. Under current cost levels, energy storage systems with power-to-capacity ratios exceeding 1/4 can profit in this market. From the perspective of energy storage participants, if market prices for distributed electricity transactions are higher than 0.74 ¥/(kW∙h), and the price difference between peak and off-peak electricity sales is greater than 0.4 ¥/(kW∙h), market participants can gain 2.4% to 14.3% more profit through energy storage sharing than through grid backup mode. Conversely, when market prices are lower and price differences are smaller, participants may earn 0.71% to 10.69% less through energy storage sharing. Thus, under specific market conditions, distributed energy storage sharing can create mutually beneficial transactions. Additionally, blockchain technology supports an automated end-to-end trading process, including transaction submission, matching, energy usage rights transfer, on-chain data storage, and real-time settlement. The following conclusions can be drawn from the simulation analysis: (1) The profitability of energy storage participation in the sharing market is subject to the constraints of initial construction, operational costs, and the parameters of energy storage devices. Technological improvements, coupled with cost reductions, are expected to promote the development of the energy storage sharing market. (2)Market conditions characterized by significant fluctuations in grid electricity prices and high levels of trading prices for distributed electricity are more likely to attract market participants to engage in energy storage sharing transactions. (3)Blockchain technology ensures transparency and traceability in energy storage sharing transactions while enhancing the trust of energy storage sharing participants in the platform. This provides robust technical support for the further implementation and promotion of distributed energy storage sharing transactions. © 2024 China Machine Press. All rights reserved.

Abstract :
With the goal of 'carbon peaking and carbon neutrality', the process of carbon reduction in the power industry has been accelerated. The carbon emissions trading, the green certificate trading and the excessive renewable electricity consumption trading have become important market instruments to reduce carbon emissions and promote the development of new power systems. First of all, based on the bilateral centralized bidding, this paper establishes a power energy market trading mechanism considering the coupling of the carbon-green certificate–renewable electricity consumption market with the participation of thermal power, wind power, photovoltaic enterprises and power users. Secondly, a hierarchical iterative interactive transaction optimization model is constructed by taking into account the optimal goals of the market members' benefits and the social welfare of the electricity markets. Finally, the alternating direction multiplier method is used for iterative solution and the impact of the carbon quota benchmark, the green certificate ratio and the renewable electricity consumption trading prices on the electricity market clearing results and the proceeds from generators and users’ costs are analyzed on the IEEE-30 node system. The results show that the power energy market trading mechanism considering the coupling of carbon-green certificate–renewable electricity consumption market is able to significantly reduce the carbon emissions of the thermal power companies compared with the single energy market trading mechanisms. Meanwhile, the mechanism can improve the wind power and photovoltaic enterprises to win the power bids, incentivize users to track the new energy output of the system and mitigate systematic wind and light abandonment. © 2024 Power System Technology Press.
