摘要
针对当下能源利用效率低以及供能系统运行成本大的普遍现象,构建了包含源网荷储多环节的虚拟电厂调度模型。虚拟电厂运行调度模型以经济性为优化目标,利用Logistic函数实现用户侧负荷的需求响应,并通过对比分析非需求响应模式、电网需求响应、电网+气网需求响应三种情况,对我国西北某工业园区进行实例分析。结果表明,对该区域实施包括电价和气价的需求响应策略后,均能实现经济优化和效率提升,其中该区域对电价的敏感性更高,为后续虚拟电厂运行调度研究提供了参考价值。
In response to the common phenomenon of low energy utilization efficiency and high operating costs of energy supply systems at present,a virtual power plant scheduling model was constructed that included multiple links of source-grid-load-storage.The virtual power plant operation scheduling model took economy as the optimization objective,used logistic function to achieve demand response of user side load,and compared and analyzed three situations:non demand response mode,grid demand response,and electric grid+gas network demand response.The case of an industrial park in northwest China was analyzed.It is known that implementing demand response strategies including electricity and gas prices in the region can achieve economic optimization and efficiency improvement.Among them,the region is more sensitive to electricity prices,which provides a reference value for subsequent research on virtual power plant operation and scheduling.
