Optimized Control of Wind Power Consumption Based on Regenerative Electric Boiler and Energy Storage System

针对三北地区冬季供热期火电机组调峰能力受限,源荷供需矛盾严重导致风电场弃风严重的问题,提出了蓄热式电锅炉融合储能的风电消纳优化控制方法。为解决风电就地消纳的难题,我国北方地区正在推广应用蓄热式电锅炉制热,增加电网的电转热负荷,以促进风电本地消纳能力;研究风电场非直接供电模式下蓄热式电锅炉和电化学储能装置的协调优化控制方法,以风电场和蓄热式电锅炉的收益最大化为目标,综合考虑风电场、电网公司及供热公司之间不同合约的情况,提出了优化的控制策略。仿真结果表明了所提方法的有效性。

Wind power curtailment prevails dramatically in winter in the Three-north Area of China,as a result of the constrained peaking capability of thermal power units and severe contradiction between power supply and demand.An optimized control method was proposed to improve the wind power consumption with regenerative electric boiler and energy storage system.The system is used for heating to increase the electric to heat load of power grid and to promote local wind power consumption.The coordinated optimized control method was discussed for the properties of regenerative electric boiler and the electrochemical energy storage device in the non-direct power supply mode of the wind farm.Considering different contracts between the wind farm company,the power grid enterprise and the heat supply company,the optimized control strategies were proposed to obtain the maximum operation profit of wind farm and regenerative electric boiler.The simulation results show the effectiveness of the proposed method.
