配电网侧广泛接入的光储系统具备成为电网调度中灵活性资源的潜力。为了提高光储系统调控的精细程度,分析建模了光储系统运行的动态特性,构建了考虑电化学模型的光储调度模型。针对保护节点用户隐私和调用分布式计算资源的需求,根据该光储调度模型给出了适用于计算的矩阵化形式,并构建了各节点处含光储系统的配电网调度优化的分布式子问题,实现了该调度优化问题的分布式求解。基于IEEE 33节点系统算例验证了所提方法的有效性。结果表明,该方法给出的调度方案在可行性、储能运行高效性和老化衰退抑制能力等方面具有优势。
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
