Abstract

Abstract:

The mechanism models of the photovoltaic and photothermal equipment，fuel cells and electrolytic cells，absorption refrigerator and air source heat pump，heat storage tank and hydrogen storage tank in an integrated energy system are established，and the constraints of energy balance in different equipment are given. According to the equipment actual conditions such as its efficiency and start-up/shutdown speed， different management and scheduling strategies are formulated， respectively. Under the constraints of energy balance， the system was tested in three different scenarios in comply with the proposed strategies. The three operation scenarios are distributing the renewable energy on load side to the energy storage system when it is excessive， and scheduling the heat and power supply mode on source side when renewable energy generation is insufficient. A simulation was carried out on the fully charged or discharged lithium batteries，and large-scale power supply and large-capacity power consumption made by fuel cells and water electrolysis were expounded. The research results can provide reference for dispatching management of integrated energy systems.

Key words: integrated energy system, modeling, characteristic simulation, dispatching management strategy, typical scenario, fuel cell, electrolyzer, air source heat pump, energy storage, renewable energy
