| 摘要: |
| 针对冷热电联供“以热定电”导致的弃风问题，提出电动汽车与地源热泵协同作用促进风电消纳的区域综合能源系统经济调度方法。首先，在源侧引入地源热泵，通过协调电源、热源出力实现联供机组热电解耦，提高风电上网空间；然后，在荷侧考虑电动汽车可调度价值，采用激励型需求响应引导充电负荷有序转移，协助风电并网消纳；最后，以调度周期内运行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，并采用优化软件CPLEX进行求解。仿真结果表明：采用地源热泵能够有效减少弃风，需求响应削峰填谷效果显著，源荷协同作用下系统风电消纳能力与运行效益更具优势，供电可靠性更高。 |

| Abstract: |
| To deal with the wind curtailment problem caused by “power determined by heat” in CCHP(Combined Cooling, Heating and Power),an economic dispatch approach for RIES(Regional Integrated Energy System) is proposed, which combines electric vehicle and ground source heat pump to promote wind power accommodation. Firstly, the operating constraints of CCHP are decoupled by adding the ground source heat pump into the source side to improve wind integration space. Secondly, the incentive demand response is adopted to guide the orderly transfer of charging load to assist wind power integration and accommodation by considering the schedulable value of electric vehicles at the load side. Finally, the source-load coordination optimal dispatch model for RIES with the goal of minimizing the operation cost is established, which is solved by the optimization software CPLEX. Simulative results show that adopting ground source heat pump effectively reduces the wind curtailment, and the peak-load shifting effect of demand response is obvious. Hence, the additional benefits are gained in terms of wind power accommodation and operation cost under the source and load coordination, and the higher power supply reliability is obtained. |
