Optimal Planning Method of Single-loop Load Storage in Distributed New Energy Multi-scale Source Network

The traditional single-loop optimization planning method of source-network load storage analyzes the energy flow of distributed new energy, but it can't obtain the collaborative planning of different regions, and it has a great impact on the environment, which leads to a poor single-loop optimization planning effect. Based on this, a multi-scale single-loop optimization planning method of distributed new energy source-network load storage is proposed. Firstly, based on the concept of load storage of the source network, the output characteristics of distributed new energy are obtained, and the mathematical model of single-loop optimization planning of distributed new energy is constructed. Aiming at the weighting process of each sub-objective function in the mathematical model, three sub-objective functions are dynamically processed, and the weight results are calculated to solve the mathematical model results of multi-scale source-network load storage single ring optimization planning. On the basis of the results, a multi-scale single-loop optimization planning strategy of source-network load storage is designed, and the multi-scale single-loop optimization planning of source-network load storage is realized according to the current calculation of the voltage outer loop. The experimental results show that the frequency control deviation of this method is small and the single loop optimization planning effect is good.
