Regional active distribution network planning study based on robust optimization

With the increasing installed capacity of new energy generation, the randomness and volatility of new energy generation has seriously affected the stable operation of the grid. And the traditional generation side dispatching method can no longer meet the demand of the grid to maintain stable operation, which greatly affects the consumption of new energy. In order to improve the rate of new energy consumption and economic efficiency, this paper proposed a regional active distribution network economic evaluation index that takes construction costs, operating costs, and new energy subsidies into account. What is more, the paper summarized the physical constraints of each equipment in the regional active distribution network. Combining the economic evaluation index and the physical constraints, the paper raised a regional active distribution network planning and scheduling model based on robust optimization. Finally, the regional active distribution network planning model based on robust optimization is validated in terms of the new energy consumption rate and the economic benefits by optimizing the examples of load-based regional active distribution network.
