考虑风险与碳流动的多虚拟电厂优化运行方法

Optimal Operation Method for Multiple Virtual Power Plants Considering Risk and Carbon Flow

为提高复杂随机碳-电市场中虚拟电厂VPP(virtual power plant)的运行水平,提出考虑风险与碳流动的多虚拟电厂优化运行方法。首先,考虑到VPP内面临的多种不确定性因素,提出自适应多损失风险计算方法;然后,考虑碳-电交易的耦合性,建立考虑多损失风险与碳流动的多虚拟电厂优化运行模型;接着,针对VPP内各元件贡献投入水平难以量化的问题,引入综合修正因子构建改进的加权Shapley值虚拟电厂效益分配模型。算例分析结果表明,所提方法能够兼顾经济效益与环境效益,提高分配的公平合理性。

To improve the operation level of a virtual power plant(VPP)in the complex random carbon-electricity mar⁃ket,an optimal operation method for multiple VPPs considering risk and carbon flow is proposed.First,in light of vari⁃ous uncertainties faced within the VPP,an adaptive multi-loss risk calculation method is put forward.Second,based on the coupling characteristic of carbon-electricity trading,an optimal operation model of multiple VPPs which takes the multi-loss risk and carbon flow into account is established.Third,in view of the problem that the contribution level of each component in VPP is difficult to quantify,a comprehensive correction factor is introduced to construct an im⁃proved weighted Shapley value VPP profit allocation model.The results of a study case show that the proposed method can take into account both the economic and environmental benefits and improve the fairness and rationality of alloca⁃tion.
