Discussion on Optimization Method of New Power System Planning Considering Short Circuit Ratio

At present, countries all over the world pay special attention to the issue of climate change, “carbon peak, carbon neutral” has become an important goal of energy development, and the traditional power grid is gradually transformed into a new power system. DC short-circuit ratio(SCR) can represent the strength of DC connected to AC system. Based on SCR calculation and comprehensive evaluation of power grid planning scheme, a new optimization method of power system planning scheme considering SCR is proposed. The adaptability of the method is verified by an example, which provides a reference for the planning and optimization of power grid with DC.
