Abstract

With the increasing consumption of energy, the efficiency of energy utilization urgently needs to be further improved. At present, the coordinated optimization control of the integrated energy system of multiple types of cooling, heating, and power equipment is an important way to improve the comprehensive energy efficiency of the regional power grid and reduce the operating cost of the power grid. Aiming at this scenario, this paper establishes a fine energy storage model by analyzing the uncertainty of wind power output and considering the influence of low temperature and other conditions on the energy storage device in the energy storage side. On the load side, the influence of comprehensive demand response of electricity and heat on system operation is analyzed, and a combined cold, heat, and electricity supply system including renewable energy and energy storage device is established. Aiming at the optimal total cost of the integrated energy cooling and heating triple power system collaborative optimization control, the crow search algorithm is used to iteratively optimize the configuration model of the triple power system. The four models are considered in the article include groundless heat pump and energy storage, excluding joint demand response, including ground source heat pump and traditional energy storage model, excluding joint demand response, including ground source heat pump and fine energy storage model, excluding joint demand response, including ground source heat pump and fine energy storage model, taking into account the joint demand response. The simulation results show that the cooperative optimization control strategy of the combined cooling, heating, and power system with renewable energy and fine energy storage device model can enhance the system’s schedulable space, improve the comprehensive energy utilization efficiency, and have considerable economic benefits.

Summary

Introduction

As the most basic driving force for the growth and development of the national economy, is the basis for human survival, and it is the current research focus of the international community. The integrated energy system has developed rapidly at home and abroad due to its characteristics such as the ability to absorb new energy In this regard, because the combined cooling heating and power (CCHP) technology can meet the demand for refrigeration and meet the demand for cogeneration, and the economy is getting higher and higher. Literature [9] proposes a two-stage robust scheduling model of MES that considers integrated thermal and power demand response (DR) to drive robust operation decisionmaking. This paper establishes a refined energy storage model, considers the consumption of renewable energy, and proposes an optimized control strategy to solve these problems.
