摘要：

园区综合能源系统具有供能子系统繁多的特点，亟需对多个供能子系统进行协调优化调度以提高系统运行经济性。为此，提出一种基于“端-边-云”架构的园区综合能源系统协调优化调度方法。该方法考虑园区中相邻供能子系统之间的电、热、气互济互补，在云端建立综合能源系统优化模型，在边缘侧利用同步型ADMM算法求解调度方案，在端侧将最优化调度方案下控至各用能设备。算例结果表明，所提优化调度方法可有提升系统运行的经济性与可靠性，并缓解调度中心的计算压力。

Abstract:

The comprehensive energy system in the park has the characteristics of many energy supply subsystems. It is critical to coordinate and optimize multiple energy supply subsystems to improve the system's economic operation. Therefore, a coordinated and optimized scheduling method for the park's integrated energy system is proposed, based on an "end-edge cloud" architecture. In this method, considering the mutual economic complementarity of electricity, heat, and gas between adjacent energy supply subsystems in the park, an integrated energy system optimization model is established in the cloud, the synchronous ADMM algorithm is used to solve the scheduling scheme on the edge side, and the optimal scheduling scheme is controlled for each energy consuming equipment on the end side. The example results show that the proposed optimal scheduling method can improve the economy and reliability of system operation, as well as relieve the dispatching center's computational pressure.

Key words: end edge cloud, carbon capture (CCS), electricity to gas (p2g), synchronous ADMM, park comprehensive energy
