Research on Rolling Optimal Scheduling Model of Integrated Energy System for Park Energy Internet

As the physical carrier of the energy internet, the reasonable scheduling of the integrated energy system has become the focus of current research. In this paper, based on the demand for energy internet construction, renewable energy and demand- side load fluctuations are considered, and the price-type and substitution-type demand side response characteristics are utilized to establish day-ahead and intra-day optimization scheduling model, which takes into account the demand side response. According to the difference of electricity, cold/heat and gas dispatching time, a three- layer rolling optimal dispatching model is proposed. The case study shows that the multi-time scale optimal scheduling model with demand-side response can restrain the fluctuation of intraday renewable energy and load, improve the stability of the system, and further reduce the operating cost of the system.
