Virtual Power Plant Energy Efficiency Management System Considering Thermostatically Controlled Load

With the continuous development and progress of China's social economy,the demand for electricity and energy from all sectors of society has become larger and larger,and the problems of energy shortage and underutilization that have been exposed have attracted the attention of the state.Therefore,through the distribution and management of power energy on the supply side and the demand side of the virtual power plant,the scientific,intelligent and refined power energy management is realized,and the purpose of saving energy and protecting the environment is becoming more and more clear.In recent years,the thermostatically control load capacity has increased rapidly in China,and a large number of thermostatically control loads have also brought huge regulatory potential.In this context,this paper realizes the “shift peak filling” of electric power through the analysis and research of thermostatically controlled load,and then optimizes the dispatching of energy efficiency management system of virtual power plant,which is helpful to alleviate the contradiction between power supply and demand,ensure the safe and stable operation of power grid,and improve Energy efficiency is of far-reaching significance for China's optimal allocation of power resources.This paper firstly explains the background and significance of the thermostatically controlled load participating in the virtual power plant to complete the demand side response,analyzes the domestic and foreign research status of the thermostatically controlled load participation demand response,and expounds the virtual power plant and its realization basis,and the demand side management.The concept and related structural design were expounded,and the selection of thermostatically controlled load and the capacity characteristics and working characteristics of the load were studied.Secondly,the demand response of thermostatically controlled load based on virtual power plant is expounded.The function of virtual power plant energy management system based on demand response is introduced.In order to apply theregulation strategy of virtual power plant for thermostatically controlled load,the air conditioning load and electric water heater load are understood.The thermodynamic model plays an important role in the design and implementation of energy efficiency management systems.Finally,the hardware and software components of the FPGA-based power monitoring device are designed,including the functions of collecting basic energy parameters,recording three-phase unbalance and zero-sequence current.In terms of control,data interaction between the upper and lower computers is performed through the ZigBee network setting.A man-machine interaction interface of energy efficiency management system of virtual power plant based on thermostatically controlled load is designed to realize remote monitoring of thermostatically controlled load.
