摘　　要：为解决西北地区大规模风电接入下系统弃风限电问题,提出一种考虑源–荷多时间尺度协调优化的大规模风电接入多源电力系统调度策略,该策略通过协调调度源侧常规火电机组、光热(concentrated solar power,CSP)电站与风电出力以及荷侧各类需求响应(demand response,DR)资源调用计划,在促进系统风电消纳的同时提高了系统运行经济性。首先,根据响应速度的不同对DR资源进行分类;然后,综合考虑CSP电站的能量时移特性与快速调节能力以及DR资源的多时间尺度特性,以系统运行成本以及弃风惩罚成本最低为目标,构建了源–荷多时间尺度协调调度模型。IEEE-30节点算例结果表明所提出的调度策略能够协调优化源–荷侧可调节资源,有利于提高系统风电消纳能力并改善系统运行经济性。This paper presents a scheduling strategy of wind penetration multi-source system considering multi-time scale source-load coordination for the wind curtailment in the northwest region in China.The strategy increases the accommodation of wind power while improving the economics of the system by coordinating the conventional generators,concentrated solar power plant(CSP)and the wind output on the scheduling source side,and the resources of demand response(DR)on the load side.Firstly,the resources of DR have been classified by their response times.Then,this paper builds a source-load multi-time scale scheduling model,combining the energy time shift characteristics and rapid adjustment capability of a CSP plant with the multi-scale characteristics of the DR resources.The objective of this model is to minimize the cost of wind curtailment and system operation.Finally,the studied simulation results in an IEEE-30 bus system show that the strategy proposed in this paper can coordinate the adjustable resources of the source and load and increase the accommodation of wind power while improving the economics of system.
