Design of building integrated photovoltaic system to the grid with power quality improvement features for Central African countries

Economy of Central African countries is growing very fast and the energy demand is increasing daily. As a result, the insufficient of electrical power generation is one of the major problems that slow the development. This paper is mostly focused on a technical and economical feasibility study of building integrated photovoltaic system (BIPVS) supposed to be compatible with the local consumption habit. To achieve this goal, a model of building with 263 kWh daily consumption is studied. A high efficiency dc-ac converter is modeled and controlled to interface the integrated photovoltaic system with the grid and building. A sliding mode algorithm is used to control a dc-dc converter for extracting the maximum available power from photovoltaic system. For emergencies, a battery pack is designed to supply sensitive equipment and lighting. The studied system is validated using the professional PV*SOL software and "Matlab/ Simpower system". The results are promising and could be an efficient solution to the mentioned problems.
