摘要
充分利用灵活性资源的调节能力可有效平抑新能源出力的波动,保证系统经济安全运行。提出一种计及电池储能和抽水蓄能灵活性的电力系统优化调度方法。在建立向上/向下灵活性需求模型的基础上,以调度能量成本、备用成本和灵活调节服务调用成本的总成本最小为目标,建立基于日前安全约束机组组合和实时经济再调度的混合整数线性规划模型,采用CPLEX进行求解。以IEEE-RTS-24节点系统为算例,考虑4种不同典型方案场景,对比验证了所提方法能有效提升系统运行灵活性,降低运行成本。
Making full use of the regulation of flexible resources can effectively suppress the fluctuation of renewable energy generation and ensure the economic and safe operation of power system.An optimal dispatching method for power system considering the flexibility of battery energy storage systems(BESS)and pumped hydro energy storage(PHES)was proposed.Based on the establishment of the flexible ramp-up(FRU)and flexible rampdown(FRD)requirement model,a mixed-integer linear problem(MILP)based temporal day-ahead securityconstrained unit commitment and re-dispatch with the objective of minimizing the cost of energy,reserve,and flexible ramp products(FRP)was formulated for the studies,which was solved using CPLEX solver.The IEEERTS-24 node system was taken as an example and the proposed model was studied on 4 cases to verify that the proposed method can effectively improve the operational flexibility of power system and reduce operating cost.
