Abstract

This paper presents an energy management systemfor a Net-Zero Energy House. The house is equipped with photovoltaic panels on the roof, a stationary energy storage system, and a Battery Electric Vehicle. The energy management strategy aims to minimize the house interaction with the power grid, enabling internal power flow without impacting upstream of the point of common coupling. The goal is to ensure that the house predominantly operates as a self-sufficient energy system, with the capability to even inject surplus energy back into the grid. The proposed topology and operation strategies are presented and validated through simulation results.

Key words: nZEH, PV panels, stationary battery electric vehicle.
