The distribution network is directly connected to the user side, making its position critical. Demand-side response enables users to actively participate in distribution network scheduling, which plays a vital role in ensuring both the security and economic operation of the network. Therefore, incorporating demand-side response for optimal scheduling in new energy distribution networks is crucial. This paper focuses on the following aspects: First, the components and advantages of new energy active distribution networks are examined, and a detailed model of incentive-based demand-side response is developed. Then, an optimal dispatch model is established with economic efficiency as the primary objective, solved using an improved particle swarm optimization algorithm, and tested with the IEEE 33-node distribution network standard. Finally, data analysis reveals that with the participation of demand-side response, the new energy distribution network operates with enhanced economic efficiency.
