Power systems that combine solar power from a photovoltaic system with a wind power generating energy source. The PV System has hardly any marginal cost and is treated with priority on the grid. The wind power generators are used to constantly fill in the gap between the present load and the actual generated power by the PV system. As solar energy is fluctuating, and the generation capacity of the wind power generators is limited to a certain range, it is often a viable option to include battery storage in order to optimize solar's contribution to the overall generation of the hybrid system.
