摘要 针对面向"源-网-荷-储"的主动配电网(active distribution network,ADN)的协调优化运行问题,首先提出了考虑分布式电源(distributed generation,DG)、电池储能系统(battery energy storage system,BESS)接入下的主动配电网日前协调优化运行模型。模型以1天24 h内的网络损耗为优化目标,考虑DG、BESS等的时序特性,基于多时段配电网络重构及BESS运行优化达到"源-网-荷-储"的协调优化。之后采用二阶锥规划(second order cone programming,SOCP)方法对模型进行求解。最后采用IEEE 33节点算例进行验证,分析了不同DG、BESS接入容量下,ADN协调优化运行结果。结果表明所提的协调优化运行模型能大幅降低系统网络损耗、提高系统的运行特性。 Aiming at the coordinated optimization problem of"generation-grid-load-energy storage"in active distribution network( ADN),this paper proposes the day-ahead coordinated optimal operation model considering the integration of the distributed generation( DG) and battery energy storage system( BESS). The mathematical model takes the active power loss within 24 hours as the objective. The timing characteristics of DG and BESS are considered. Multiple interval distribution network reconfiguration and BESS optimal operation are taken as the active measures for the "generation-gridload-energy storage"coordination. The second order cone programming( SOCP) method is used to solve the model. IEEE33-node system is selected for the verification. Different capacities of DG and BESS are analyzed for the coordinated optimization problem. The result shows that the coordination can largely decrease the active power loss and improve the system operation characteristic.
