Abstract:
Focusing on the goal of carbon peak and carbon neutrality, the low-carbonization of the whole link of energy power system(i.e., source-network-load-storage) faces new requirements and challenges. The high proportion of renewable energy generation has become an inevitable trend.Considering the impact of the uncertainty of renewable energy generation on the safe and stable operation of the power system, the use of virtual power plant(VPP) with multi-energy complementary characteristics is a favourable way to solve this problem. Therefore, an optimal scheduling strategy of multi-energy complementary VPP was proposed.Firstly, taking into account the coupling relationship between multiple energy sources, a VPP operation mechanism that takes into account the entire source-grid-load-storage chain was constructed. Secondly, according to the proposed operation mechanism, a multi-energy complementary optimal dispatching model with low carbon economy as the goal was proposed to promote the consumption of renewable energy by coordinating the dispatching of various types of devices.Finally, the effectiveness of the proposed strategy was verified by simulating and analyzing a reference case of a multienergy complementary VPP including renewable energy generation in a region.
