Research on Multi-time Scale Optimal Operation Strategy of Customer-side Integrated Energy System

In the traditional power demand response, users can help the power system to complete peak and frequency modulation while reducing their own electricity costs by means of reduction and translation. For the customer-side integrated energy system (CIES), the load demand of users becomes diversified, and scientific and reasonable optimal operation strategy is particularly critical. Based on the constructed CIES internal equipment model and the static and dynamic characteristics of its flexible resources, this paper proposes an optimal operation strategy for participating in the demand side response of the power grid at multiple time scales. A day-ahead and intra-day two-stage optimal scheduling model is constructed, and an example is used to verify the effectiveness of the proposed strategy.
