摘要：
Insufficient flexibility of power system and transmission congestion are two fundamental reasons for wind power curtailment, and they have a certain coupling relationship in time sequence. From the perspective of time-sharing reuse of energy storage, this paper uses the coupling relationship between wind power curtailment events to solve the problem of insufficient peak shaving and transmission congestion at the same time by configuring energy storage, and proposes a source-storage-grid joint planning method considering the coupling relationship of wind power curtailment events. Firstly, the generation mechanism of wind power curtailment due to insufficient peak regulation, blocking wind power curtailment and their coupling relationship are analyzed. Then, the influence of energy storage configuration on the installed capacity planning of source-side conventional units and the configuration of grid-side transmission capacity is analyzed. Secondly, this paper constructs a joint source-storage-grid planning model considering the conventional thermal power installation investment cost, energy storage investment cost, wind power curtailment penalty cost and transmission line expansion cost, and gives the solving process of the model. Finally, the effectiveness and feasibility of the proposed method are verified by the simulation of the transmission engineering system of a local power grid in Northeast China and Garver-6 node system. © 2023 Automation of Electric Power Systems Press.
