Research on Optimal Operation of Multi-Time Scale Cold-Thermal-Electric Integrated Energy System

The integrated energy system with multi-energy complement and high energy utilization rate as the core has attracted more and more attention. System economy optimization is regarded as the goal based on the multi-time scale optimization model with different time response characteristics of cooling, heating and electricity in the paper. Equipment model constraints and power balance constraints are considered. The branch and bound algorithm is adopted to solve the optimization model. The calculation results show that the system power is balanced, and more time margin is available to regulate system equipment output, and the operating condition of equipment is stable, thereby realizing the purpose of multi-energy complement and efficient utilization.
