为了就地消纳大规模风力发电功率和提升电网调峰能力,将蓄热式电采暖与具有反调峰特性的风电进行结合,提出了风电与蓄热电采暖联合运行模式。模式中考虑风电机组、火电机组以及电采暖的相关约束,以系统总的发电成本最小为目标,构建了蓄热式电采暖负荷参与风电消纳优化运行模型。通过运用适应模型求解的遗传算法求解该模型,得到蓄热式电采暖负荷参与电网互动优化运行方案。仿真结果表明,基于蓄热式电采暖负荷参与风电消纳的运行策略是有效和实用的。该策略从电源侧的角度提高了系统的风能消纳水平,从电网侧的角度提升了系统的调峰能力,缓解了风电并网对系统造成的调峰压力。

Research on operational strategy for regenerative electric heating load participating in wind power consumption

In order to absorb large scale wind power generation and improve the peak shaving capacity of the grid,regenerative electric heating is combined with wind power possessing anti-peak regulation characteristics and a joint operation mode is established.In this mode,we consider the related constraints of wind turbines,thermal turbines,and regenerative electric heating.This has the goal of minimizing the total power generation cost of the system.An optimal operation model of regenerative electric heating load participating in wind power consumption is constructed.The adapting genetic algorithm is used to solve the model and the regenerative electric heating load participation in the grid interactive optimization operation strategy is obtained.The simulation results show that the operational strategy is effective and practical,and improves the wind power absorption level of the system from the perspective of the power source side,enhances the peak regulation ability of the system from the perspective of the grid side,and alleviates the peak shaving pressure caused by wind power connection to the power system.
