摘要
针对区域综合能源系统(RIES)中热电联产机组(CHP)“以热定电”运行方式导致的弃风现象,提出一种考虑地源热泵与电热综合需求响应协同配合风电消纳优化调度方法。在源测构建包含风机、光伏、储能、地源热泵与CHP的RIES模型,利用地源热泵协同配合CHP运行出力,消纳并网风电,解耦CHP “以热定电”运行约束,提升风电上网空间;在荷测针对电、热柔性负荷可调度价值,引入电价型和激励型两类需求响应(DR)协同风电并网消纳;以系统调度成本最小为目标建立源荷协同区域综合能源系统优化调度模型,决策各机组最优出力;基于商业求解器CPLEX进行多场景对比分析。结果表明:该策略可有效降低系统总调度成本,实现风电全额消纳,具有良好的社会经济效益。
In view of the phenomenon of wind curtailment caused by"thermal fixed power"operation of combined heating and power(CHP)units in regional integrated energy system(RIES),an optimal scheduling method for wind power consumption considering the coordination of ground source heat pump and electrothermal comprehensive demand response is proposed.The RIES model including fan,photovoltaic,energy storage,ground source heat pump and CHP is constructed in the source test,and the ground source heat pump is used to cooperate with the operating output of CHP,absorb grid-connected wind power,and decoupled the CHP operation constraint of"heat to power"to improve the Internet space of wind power;according to the dispatchable value of the flexible load of electricity and heat,two types of demand response(DR)of electricity price type and incentive type are introduced to cooperate with the grid-connected wind power;the optimal scheduling model of the source-load cooperative regional integrated energy system is established to minimize the system scheduling cost,and the optimal output of each unit is determined;based on the commercial solver CPLEX,a comparative analysis of multiple scenarios is carried out.The results show that by using this strategy,the total dispatching cost of the system can be effectively reduced,the full absorption of wind power can be realized and has good social and economic benefits.
