摘要：
Aiming at the problems of increasing disturbance uncertainty and insufficient active power control resources under the integration of high proportion of renewable energy, a robust optimization configuration method for energy storage system (ESS) capacity considering the uncertainty of disturbances is proposed. Firstly, based on the extended system frequency response model, the coupling relationship between ESS operation power and system frequency dynamics is extracted, and the constraints of transient frequency deviation security are constructed from the polyhedral uncertainty set of disturbance. Secondly, taking into account both the frequency stability control capability and the uncertainty of disturbances, a robust optimization model is established with the objectives of minimizing investment costs and maximizing operation benefits. Then, the linear weighted method and robust counterpart are used to transform the optimization model into a deterministic tri-level program, which is solved by using the column-and-constraint generation method, strong duality theorem, and Big-M method. Finally, the effectiveness of the proposed method is verified through case analysis. © 2024 Automation of Electric Power Systems Press. All rights reserved.
