Abstract :
In recent years, typhoons and rainstorms have increasingly become the typical natural disasters that affect the safe and stable operation of distribution networks in coastal cities. To effectively cope with the influence of extreme disasters, a multi-stage resilience enhancement strategy is proposed for distribution networks, considering the spatiotemporal uncertainty of typhoon rainstorm disasters. Firstly, the disaster scenarios are simulated according to the historical data of typhoons, and the failure probability of distribution lines is calculated to construct an uncertainty set for the typhoon rainstorm disaster attack. On this basis, combined with the non-anticipativity characteristics of the power system scheduling process, a multi-stage robust optimization model based on the uncertainty set above is established. Secondly, a pre-extended robust dual dynamic programming algorithm is developed for solving. Then, the pre-disaster defense strategies and well-trained worst-case cost-to-go functions during disasters are obtained, which can solve the emergency response strategies for each period of extreme disasters. As a result, the optimal resilience enhancement strategies for distribution networks have been made in an organic combination of offline training and online application. Finally, the test systems for distribution networks with different scales are used to verify the effectiveness of the proposed model and method. © 2025 Power System Technology Press.

Abstract :
The large-scale integration of electric vehicles and distributed power sources will further exacerbate the peak valley load difference in power systems, which has posed a serious challenge to the stability and economic operation of the hybrid AC/DC distribution network. A hierarchical decentralized coordinated scheduling framework for the hybrid AC/DC distribution network coupled with the photovoltaic-storage-charging integrated stations considering multiple uncertainties is firstly proposed. In this framework, a multi-objective optimization model with the pursuit of the minimum day-ahead operation cost and peak valley difference of net load is presented for the distribution network, which is solved by the normalized normal constraint method. On the other hand, a two-stage robust optimization model considering a virtual battery model and source-load uncertainty set is established for the integrated station, which is solved by the column-and-constraint generation algorithm. Furthermore, an improved alternating direction method of multipliers is developed to solve the above decentralized optimization problem. Finally, the proposed model and solving method are validated via a modified 33-bus hybrid AC/DC distribution network coupled with 3 integrated stations. Simulation results demonstrate that the multi-objective scheduling strategy can achieve prominent effects of peak shaving and valley filling compared with the single-objective strategy. Specifically, the peak valley difference of net load has reduced by 70.1 %. Moreover, the coordination operation of various controllable devices can improve the operation flexibility of power systems and alleviate the influence of the multiple uncertainties. In addition, the solving time of the proposed method has shortened by 39.9 % compared with the traditional algorithm.

Abstract :
A surge in EVs is bound to greatly impact on urban power grids and transportation networks. Studying how to accurately describe the impact of electric vehicle behaviors on the power-transportation network is of great significance. This paper considers the elasticity of demand for electric vehicles and their charging behaviors and introduces the quasi-variational inequalities (QVIs) to address the complexity of the game behavior modeling in the coupled network as well as its solution challenges. First, a hybrid traffic flow model is built, which includes the elastic demand and charging behavior of EVs. On this basis, a QVI framework is proposed to characterize the elastic mixed user equilibrium state, and its equivalence to the equilibrium state is proved. Secondly, a second-order cone programming model for the distribution network considering charging loads is proposed, and the coupling relationship between the two networks is established. Then, the mechanism of the coupled network is described as a double-layer game problem using fixed-point mapping. Given the characteristics of inner and outer game problems, an outer fixed point iteration algorithm and an inner viscous projection approximation algorithm are developed respectively to form a complete method for identifying the equilibrium state of the two-layer game. The simulation based on a test system in Fuzhou verifies the effectiveness of the modeling and solving methods in this paper, which shows the necessity of considering the elastic demand of EVs for the equilibrium state analysis of the coupled networks. ©2024 Chin.Soc.for Elec.Eng.

Abstract :
With the large-scale development of electric vehicles, it is of great significance to study how to effectively consider the travel behavior mechanism of users and formulate rational charging prices for charging stations for the collaborative optimization and scheduling of power-transportation networks. To solve this problem, this paper proposes a pricing strategy for charging stations in the power-transportation coupling network considering the user travel cost budget. Firstly, a transportation user equilibrium model considering the travel cost budget is established, and the equilibrium state is equivalently described through variational inequalities, so as to characterize the travel demands and charging behaviors of electric vehicles. Secondly, a second-order cone optimization model for distribution networks considering power reduction is constructed. The charging station pricing problem has been transformed into an optimization problem with variational inequality constraints, and an alternating iteration algorithm combined with an extra-gradient algorithm is designed to solve the problem. Finally, the effectiveness of the proposed model and methods is verified through a case, and the results show the necessity of considering the travel cost budget for charging pricing in coupled networks. © 2024 Automation of Electric Power Systems Press.

Abstract :
For the low carbon economic operation problem of power system,a collaborative optimization method for the configuration-operation of coal-fired power plants with carbon capture considering low-carbon demand response is proposed. The operation data of solvent-based carbon capture coal-fired power plants is collected on the gCCS platform,taking into account the strong coupling relationship between the power generation system and the post-combustion carbon capture system. The model parameters are identified by multiple linear regression method,and the corresponding steady-state mathematical model is constructed. The carbon emission flow theory is used to calculate the carbon emission cost on the load side,and the carbon quota is allocated according to the carbon emission intensity of generator units. And then a low-carbon demand response model is established. On this basis,the upper-level optimization model takes the lowest power plant configuration cost as the objective function to meet the capacity optimization allocation constraints. The lower-level optimization model with the goal of minimizing operating cost is established to meet the system operation constraints. The simulation analysis is implemented on the modified IEEE 24-bus system,by which the effectiveness of the proposed strategy is verified. © 2024 Electric Power Automation Equipment Press.
