A Multi-Energy System Cluster Operation Optimization Method Based on Nanocomposite Electrode Materials Energy Storage Equipment

Abstract

A cluster operation optimization method of multi-energy system is proposed based on nanocomposite electrode materials energy storage in this paper, aiming at the difficulty in power balance coordination control of regional-level multi-energy systems due to the rapid growth of renewable energy power generation. In this method, the dynamic influence of nanocomposite electrode materials on the peak power of energy storage is fully considered. The power balance adjustment capability of the multi-energy system is effectively improved by this method. First, an operation optimization control model of multi-energy system cluster based on nanocomposite electrode materials energy storage equipment is established based on the peak power of energy storage, the joint response of renewable energy, thermal and hydrogen energy, and the operation characteristics of multi-energy systems. Then, the multi-energy system cluster coordinated operation strategy model and its solution algorithm based on the maximum renewable energy consumption and operating benefit are studied. Finally, a PSCAD simulation model based on the IEEE 14-nodes system is established. The simulation results and analysis show that the multi-energy system cluster operation optimization model based on nanocomposite electrode material energy storage equipment can effectively improve the power balance ability of the multi-energy system under the condition of the uncertainty of renewable energy. And this method can reduce the cost of grid operation and power regulation, and improve the efficiency of refined energy management of energy storage.
