Optimization Strategy of Multiarea Interconnected Integrated Energy System Based on Consistency Theory

Abstract EN

A collaborative optimization strategy of an integrated energy system aiming at improving energy efficiency is studied in this paper for the cluster optimization of an integrated energy system (IES).

In this paper, an improved discrete consistency method based on the coordination optimization method for IES is proposed.

An IES model considering the mixed energy supply of electricity, heat, and gas is constructed in a single region.

And then an objective function with the maximum return is established, on the premise of assuming that the prices of electricity, heat, and gas can be used as an economical means to adjust the energy utilization.

Finally, the consistency theory is applied to the IES, and the improved discrete consistency algorithm is utilized to optimize the objective function.

In the case study, a certain region IES is taken as an example in Northeast China.

The case study demonstrates the effectiveness and accuracy of the coordination optimization method for IES.
