Using a flywheel associated to PV power plant in order to increase the integration of PV into island electrical grid

Abstract

In a context where renewable energies from both wind and solar energy have low predictability, low controllability and strong variability, their massive integration into power systems may cause instabilities for these grids. The use of storage energy system is a promising solution. In the present article, we propose to focus on a detailed photovoltaic model in order to test flywheel energy storage system (FESS) models. FESS is used to smooth photovoltaic energy for power quality. A 17-kW photovoltaic grid connected power plant is modelled with Matlab/Simulink/SimPowerSystems.
