Energy Saving Programming of Distribution Network Considering High Permeability Renewable Energy Access

In view of the increasing proportion of renewable energy access in distribution network, the traditional programming method was unable to meet the needs of power grid development. A hierarchical and zoned energy-saving programming method for distribution network with high proportion of renewable energy was proposed. Firstly, the capacity and layout of high proportion renewable energy were optimized to realize the initial site selection and capacity determination of renewable energy. Secondly, taking the renewable energy planning results as the initial value, a bi-level iterative programming model was constructed to realize the optimization decision making model with cost and energy-saving benefits as the goal. Finally, the harmony search algorithm was used to solve the proposed optimization model. The real power grid data is used for analysis. The simulation results show the effectiveness and feasibility of the proposed model and method.
