摘要：
The widespread of photovoltaic-battery storage systems (PBSSs) in the distribution networks provides considerable potential of flexible resources in power grid dispatch. To enhance the control fineness of the PBSS, the operation dynamic characteristics are analyzed and modeled while the dispatch model of PBSS considering electrochemical model is developed. With the expectation of preserving users’privacy and utilizing distributed computational resources, the matrix form of the dispatch model is put forward and the distributed subproblems of each node for scheduling optimization of the distribution network are presented and solved by the distributed computing. The proposed method is validated in the case study of IEEE 33-bus system. The results show that the proposed method achieves superiority in terms of the feasibility of the dispatch plan, the operation efficiency of energy storage, and the suppression of aging. © 2024 Automation of Electric Power Systems Press.
