Abstract
The effect of indeterminacy of distributed generation should be fully considered in the planning of active distribution network. Based on the conventional load forecasting, the trusted output model of distributed generation connected to active distribution network is built. Thinking the influence of load demand side response on the forecasted load results, a distribution network load forecasting model considering the multiple synergistic interaction effect of source, load and storage is proposed. Based on the results of load forecasting, a double-deck multi-objective programming model of active distribution network is established. The upper deck function is the problem of power grid optimization planning, and the goal is to minimize the annual network comprehensive cost; The lower level programming model determines the active power output of manageable resources such as energy stored based on the typical daily system operation economy under the grid achieved by the upper part planning. Through the optimization solution, the distribution network planning scheme and the location and capacity scheme of energy storage under the active management mode are obtained. In result, we use an active distribution network in Shanghai to prove the scientificity and effectiveness of the proposed programming method
