摘要: 含氢储能的热电联产型虚拟电厂通过结合聚合资源的热电联产特性,为氢储能参与电网调度、消纳新能源等提供了新的路径。首先,充分考虑氢储能的热电联产特性,在满足热、电负荷需求的条件下,建立虚拟电厂综合运行成本最小的日前调度优化模型,决策聚合资源的日前出力计划。其次,考虑负荷侧用氢需求,包括氢能公交车、氢能汽车氢燃料需求,建立日前用氢需求预测模型。然后,将用氢需求作为约束条件嵌入虚拟电厂日前调度优化模型中,得到考虑氢负荷需求下虚拟电厂的优化运行策略。最后,某园区的仿真分析结果表明,考虑售氢收益的虚拟电厂优化调度策略相较于传统的只考虑氢储能热电联产特性的虚拟电厂调度策略,运行成本降低了24.6%。

Abstract: The cogeneration virtual power plant with hydrogen storage provides a new path for hydrogen storage to participate in grid scheduling and consume new energy by combining the cogeneration characteristics of the aggregated resources. First, the cogeneration characteristics of hydrogen storage energy are fully considered, and the day-ahead scheduling optimization model that minimizes the comprehensive operating cost of the virtual power plant is established to make decisions on the day-ahead output plan of the aggregated resources under the condition of meeting the heat and electricity load demand.Then,the day-ahead hydrogen demand forecast model is established by considering the load-side hydrogen demand, including the hydrogen fuel demand of hydrogen buses and hydrogen cars. Next, the hydrogen demand is embedded as a constraintinto the virtual power plant day-ahead scheduling optimization model to obtain the optimal operation strategy of the virtual power plant under the consideration of hydrogen load demand. Finally,a simulation analysis in a park is conducted, and the results show that the operating cost of the optimal scheduling strategy of the virtual power plant considering the revenue from hydrogen sales is reduced by 24.6% compared with the traditional virtual power plant scheduling strategy only considering the characteristics of hydrogen storage cogeneration.
