Model predictive control of combined renewable energy sources

This paper proposes strategy to maximize the use of renewable energy on islanded grid. Photovoltaic will be used as main electricity source to supply home load. Lack of electricity will be supplied by picohydro power plant (PHPP). Deficit of electricity supply is utilized as set point reference by a controller implementing model predictive control (MPC) to regulate the flow control valve which feed water to PHPP turbine generator. A comparison of results between PI and MPC is presented. The method is verified using simulation result.
