New Power System Topology Transformation Planning Method

To address the issue of the consumption cost of new energy, a two-tier optimization model is proposed, considering the coupling relationship of source-load equipment. The upper-level planning model aims to minimize the annual net present value cost, with the decision variables being the installation capacity of energy equipment. The lower-level operational model aims to minimize the consumption cost of new energy, with the decision variables being the scheduling values of peak-shaving devices. Through case studies, it is confirmed that the consumption cost is significantly reduced using this model.
