摘要:

分布式能源大规模并网加剧了电力系统的不确定性、波动性和随机性。本文提出了一种基于模拟退火(simulated annealing,SA)的启发式算法,以及结合了建筑能源模拟Energy Plus软件/模拟配网的Matpower软件的协同仿真框架,实现了配电网负载均衡和损耗最小化问题的公式化,在配网层面研究了应对线路故障(如断线)的负荷均衡和功率损耗最小化策略。基于需求响应(demand response,DR)信号实现了分布式用户的电池储能系统(battery energy storage systems,BESS)的合理调度。本工作采用一个9节点网络进行仿真验证,并赋予模型不同权重系数。研究结果表明,所提算法对分布式能源接入配电网的负载均衡和线损最小化具有准确性和可拓展性,研究结果对分布式能源接入配电网有重要的现实意义。

Abstract:

The large-scale integration of distributed energy aggravates the uncertainty, volatility, and randomness of the power system. This study proposes a heuristic algorithm based on simulated annealing and a collaborative simulation framework that combines building-energy simulation with Energy Plus/Matpower software simulating distribution network to realize the formulation of load balancing and loss minimization in the distribution network. The load-balancing and power-loss minimization strategies used for solving line faults (such as disconnection) are studied at the distribution network level. Based on the demand response signal, this study realizes reasonable scheduling of battery energy storage systems for distributed users. Finally, based on a nine-node network, the accuracy and scalability of the proposed algorithm for load balancing and line-loss minimization of the distributed energy-access distribution network are analyzed by simulating and verifying the model with different weight coefficients. The research results have important practical significance for distributed energy-access distribution network.
