Grid connected residential photovoltaic energy systems with Plug-In Hybrid electric Vehicles(PHEV) as energy storage

This paper proposes an approach for the control and optimization of power flow by integrating Plug-In Hybrid Vehicles (PHEV) to an existing residential photovoltaic system. Optimization of Power flow reduces the dependency for electric power from the grid and control involves determining the source from which residential load will be catered. The system built to achieve the goal is a combination of the existing residential photovoltaic system, PHEV, Power Conditioning Unit (PCU) and a controller. The PCU involves two DC-DC Boost Converters and an inverter. This paper emphasizes on developing the controller logic and its implementation in order to accommodate the flexibility and benefits of the proposed integrated system.
