摘要
目前新能源发电被更多地投入使用,风光资源也得到更多利用,风光发电并网规模不断扩大,但新能源发电具有的随机性及波动性,导致弃风弃光现象较严重。光热电站利用太阳能发电,具有储能系统和电加热装置,可满足调峰需求。考虑需求侧需求响应可控负荷与含光热与风电系统的调度策略,让需求响应和可控负荷及光热电站火电机组相配合一同参与风电系统调度,以系统的运行成本和弃风量最小为目标,求解最优调度计划。通过西北某地区的一典型日实测数据进行算例分析,验证该调度策略可有效提高系统的运行经济性和促进风电消纳。
At present,more new energy power generation has been put into use,more wind and solar resources have also been utilized,and the scale of wind and solar power generation connected to the grid has been continuously expanded.However,due to the randomness and volatility of new energy power generation,wind and light are abandoned seriously.Solar thermal power stations use solar power to generate electricity,with energy storage systems and electric heating devices,which can meet peak shaving needs.The demand-side demand-response,controllable load and scheduling strategies of solar-thermal and wind power systems are considered.The demand response and controllable load and thermal power units of the solar thermal power station participate in the scheduling of the wind power system,and the optimal scheduling plan is solved with the goal of minimizing the operating cost and curtailment air volume of the system.Through the analysis of a typical daily measured data in a certain area of northwest China,it is verified that the dispatching strategy can effectively improve the operating economy of the system and promote wind power consumption.
