Optimal dispatch for IES with TGC considering PV prediction error based on DRO

As the renewable energy installation incerase, self-consistent integrated energy system (IES) is becoming more and more important for power grid. However, the current optimal scheduling strategy of IES lacks of robustness. At the same time, few people have studied the influence of national policies on the optimal dispatch of IES. To solve these problems, an optimal dispatch is presented for IES with the tradable green certificate (TGC) considering PV prediction error based on distributionally robust optimization (DRO). The practicality of the proposed model is verified in the typical IES. Based on the experimental results, the proposed strategy can improve the robustness of the optimal dispatch and improve renewable energy consumption.
