Abstract

In this paper, an optimal scheduling method based on building virtual energy storage equivalent battery is proposed. Firstly, the thermal load prediction model is built based on the thermodynamic model, and then the equivalent battery model of virtual energy storage is established by combining with inverter air conditioning system model. Then, with the goal of minimizing the user’s electricity cost, considering the constraints of energy storage state and charging and discharging power of equivalent battery model, an optimal scheduling method of building virtual energy storage equivalent battery is constructed. The results show that the proposed method can predict the building thermal load, update the building virtual energy storage equivalent battery parameters, formulate the corresponding optimal scheduling strategy, and reduce the electricity cost of users for heating on the premise of ensuring the thermal comfort of users.

Highlights

Energy is the basis for human survival and the lifeblood of the national economy [1]
China's building construction and operation energy accounted for 37% of the total energy consumption of the whole society in 2018, and operating energy consumption accounted for 23%
Under the premise of ensuring the thermal comfort of users, the optimal scheduling method proposed in this paper is used to optimize the heating scheme of the office building

Summary

Introduction

Energy is the basis for human survival and the lifeblood of the national economy [1]. Building energy has become one of the world's largest energy consumption fields, accounting for more than one-third of global terminal energy consumption [2] In northern China, coal-fired heating is usually used for heating in cities and towns, which makes building energy consumption rise and environmental pollution is becoming increasingly serious. In response to this problem, China proposed a solution to "replace coal with electricity and clean heating" [4], using non-polluting, low-carbon emissions and strong controllable electric heating instead of traditional coal-fired heating to solve coal burning Environmental pollution caused by heating
