Abstract
This paper,with the Photovoltaics,Energy Storage,Direct Current and Flexibility(PEDF)building energy system as the object,and using the modular modeling method,established an overall simulation model involving HVAC(Heating,Ventilation,Air-conditioning,and Cooling)system,photovoltaic power generation system,energy storage system,electric vehicle charging pile and other subsystems.According to the real-time indoor and outdoor temperature difference,the real-time power generation and consumption of each subsystem,and the supply and demand priority of each subsystem,the power generation and consumption of each subsystem can be automatically adjusted.Based on this,an operation strategy for PEDF building was proposed,and comparative analysis and research were done from the aspects of electricity flexibility,operating economy,energy cleanliness,and system stability.The simulation results show that the PEDF building realizes the effective consumption of photovoltaics and"two-way interaction between source and load"while ensuring the thermal comfort of the human body,reduces the energy consumption costs,and improves the energy cleanliness and operation stability of building system.
