中文摘要:
      针对大规模风电并网对电力系统造成的威胁,通过充分考虑储能系统(energy storage system, ESS)与需求响应(demand response, DR)之间的有效配合,提出了一种计及ESS和DR的风水火联合电力系统经济调度模型。首先,模型将用电负荷划分为基础负荷及可调节性负荷,充分考虑了DR对可调节性负荷进行的精细化调整,有效地配合ESS装置运行,从而最小化电力系统运行总费用。其次,针对风电出力的不确定性,通过建立鲁棒优化模型确保模型具有可行解。最后,通过划分四种不同场景验证模型的有效性。仿真结果表明,考虑ESS和DR之间的互补特性后,在实现风电出力全额消纳的同时,电力系统有效地降低了运行总费用,减少了火电机组频繁启停,降低了火电机组出力的波动性。
英文摘要:
      In view of the threat of large-scale wind power integration to the power system, the effective coordination between the energy storage system (ESS) and the demand response (DR) is fully considered, and an economic dispatching model that including ESS and DR suitable for wind-hydro-thermal system is proposed in this paper. Firstly, the power load is divided into basic load and adjustable load. After the adjustable load is finely adjusted by DR, it can effectively cooperate with ESS device operation, so as to minimize the total cost of power system operation. Secondly, in view of the uncertainty of wind power output, a robust optimization model is established to ensure that the economic dispatching model has a feasible solution. Finally, the effectiveness of this economic dispatching model is verified by dividing four different scenarios. The simulation results show that while achieved full consumption of wind power output, with considered the complementary characteristics between ESS and DR, the total operating cost of the power system is effectively decreased. Meanwhile, the start-up and stop frequency of thermal power units is reduced, and the volatility of the output of thermal power units is also lowered accordingly.
