A hybrid renewable energy system integrating photovoltaic panels, wind turbine, and battery energies for supplying a grid-connected residential load

Abstract

In this paper, a topology of a multi-input renewable energy system, including a PV system, a wind turbine generator, and a battery for supplying a grid-connected load, is presented. The system utilizes a multi-winding transformer to integrate the renewable energies and transfer it to the load or battery. The PV, wind turbine, and battery are linked to the transformer through a full bridge dc-ac converter and their energy supplied to a grid-connected single-phase inverter and loads. A phase-shift control technique is employed to control the power flow between the sources and loads and the grid. To control the power flow, simple PI controllers have been used. The operation details and control techniques of the system are presented and also validated by using numerical simulations.

“…But voltage was not regulated at the required level. A wind turbine generator with a battery was employed in [2] for supplying a grid-connected load of a multi-input RE system. The phaseshift control method was introduced to manage power among sources, loads as well as grid.…”

“…In addition, onshore wind turbines affect real estate prices in nearby single-family houses and holiday resorts, reducing their value [43]. In order to fully exploit the possibilities of supplying housing estates, in addition to wind energy, photovoltaics and power supply from an external generator are also used to ensure a constant energy supply [44][45][46][47][48][49][50]. The use of natural energy sources (wind and sun) alone can be unreliable due to their unstable nature.…”
