Heat and Electrical Power Management of Residential Buildings integrated to High-Temperature Fuel Cell and Renewable Energy Systems

Abstract

This paper presents an advanced power management strategy for heat and electric power distribution of a residential building integrated hybrid renewable power sources including photovoltaic, PEM fuel cell, heat pump and Plug-in Electric Vehicles (PEV). The controllability of the fuel cell power source makes it has the main functionality role in providing heat and electric power to residential buildings. Therefore, first, the power flow structure between hybrid power resources is described. For this purpose, all necessary electrical and thermal equations are investigated. Owing to many complexities and uncertainties in this kind of hybrid system, an adaptive fuzzy sliding power control strategy is proposed to regulate the amount of requested fuel for a fuel cell power source to produce the electrical and heat power. Simulation results are illustrated to demonstrate the success and capability of proposed control strategy during charging and discharging modes of PEV.
