中文摘要:
      尖峰负荷大大降低电源装机利用率和投资效益,虚拟电厂参与调峰可有效延缓电源建设。首先,针对城市级虚拟电厂可调度容量无法精确计算的问题,提出一种考虑多领域、多评估指标的模糊区间估计方法。该方法将可调度容量估计任务分解至工业、建筑、交通领域,并构建考虑用户参与度、收益敏感度、资源可控度及可控规模的模糊区间评估模型。接着,基于可调度容量模糊估计,提出了一种考虑虚拟电厂参与调峰的电源容量规划方法。该方法在满足电源备用容量的情况下,以电源扩展安装容量最小为目标函数,考虑不同电源结构、新能源出力不确定性、虚拟电厂可调度容量等多种因素,构建电源容量规划模型。最后,以华东地区某城市为算例背景,验证所提方法的有效性。
英文摘要:
      Peak load greatly reduces the installed utilization rate and investment benefit of power supply. The participation of virtual power plant in peak shaving can effectively delay the construction of power supply. Firstly, a fuzzy interval estimation method considering multi-domins and multiple evaluation indexes is proposed to solve the problem that the schedulable capacity of urban virtual power plants cannot be calculated accurately. This method decomposes the schedulable capacity estimation task into the fields of industry, construction and transportation, and constructs a fuzzy interval evaluation model considering user participation, revenue sensitivity, resource controllability and controllable scale. Then, based on fuzzy estimation of schedulable capacity, a power capacity planning method considering the participation of virtual power plant in peak shaving is proposed. Under the condition of meeting the power reserve capacity, the power capacity planning model is constructed by taking the minimum power expansion installation capacity as objective function, considering various factors such as different power structures, new energy output uncertainty, virtual power plant schedulable capacity, and so on. Finally,a city in East China is taken as an example to verify the effectiveness of the proposed method.
