| 虚拟电厂内部资源的组合形式影响到其出力稳定性以及各分布式资源的使用效率。针对含有不同基础配置的虚拟电厂对不同DER的选择方式,提出了不同基础配置的虚拟电厂内部资源组合策略。首先对各DER的特性进行描述,之后以 VPP 在日前市场的预期收益最大化为目标,兼顾各DER运行特性以及电网约束,建立了计及DER特性的VPP内部资源聚合模型,通过算例分析得到了多场景下VPP内部资源的组合形式以及各DER的出力情况。算例结果表明,VPP内部资源组合策略随着运行场景的变化而变化,并且各个场景下VPP对可调节资源的需求均很大。相比于其他VPP,自身拥有可调节资源作为基础配置的VPP运行收益明显较大。 |

| The aggregation form of DERs inside VPP has impact on its output stability and efficiency of each DER. An internal resource aggregation strategy of VPP based on different basic configurations is proposed according to VPP’s preferences for different DERs. Firstly, characteristics of DERs are described. Then an aggregation model of internal resources, which takes into account the operational characteristics of DERs and constraints of power system, is established aiming at maximizing the VPP’s profit in the dayahead market. Multiscenario method is used to deal with uncertainty of DERs. The combination form of VPP’s internal resources and output of each DER in different scenarios are derived from the model. The results of case study show that the combination form of DERs varies with the change of operation scenarios. There is a significant demand for the flexible DERs in every kind of scenario. Meanwhile,comparing with others, VPP with flexible DERs as basic configuration can obtain a larger profit. |
