Hybrid AC/DC building microgrid architecture

Abstract

Intelligence, environmental protection, and high efficiency have always been the goals pursued in the design of microgrids. At present, building microgrids (BMGs) have become one of the most common microgrids. Based on this background, this paper aims to study the configuration optimization of BMGs, improve the connection efficiency between components, and minimize operating and investment costs. This paper firstly reviews the basic concepts of microgrid and modern smart building. And build the BMG model based on this. Building energy storage system (ESS), photovoltaic (PV) system and building load models are established. A Monte-Carlo simulation (MCS) is used to address the stochastic variations. The objective function of the model is to minimize the net operating cost (NOC). Finally, a series of case studies are conducted using this optimal dispatch model.
