Book excerpt: Major emphasis has been given on renewable-energy based generation because of their benefit of providing clean energy. Intermittency of renewable energy resources demonstrates the need for additional devices and control to help mitigate the high fluctuation in available power output; energy storage devices seem poised to provide the required support. This work presents a Hybrid Energy storage system (HESS) topology with a novel cascade control for providing load following, and voltage support benefits. System level analysis is detailed using Photovoltaic as sustainable micro-source. In this thesis emphasis had been given on dynamic model development of HESS components - Batteries and Ultra-capacitor. Integrated HESS with cascade control has been developed. Validation and dynamic analysis of the system and its components has been presented using electro-magnetic transient program PSCAD/EMTDC. Verification of the cascade control scheme has been detailed for various cases of dynamically changing load profiles. Lastly, analysis of integrated photovoltaic and hybrid-energy storage system is demonstrated by introducing variability in the available solar production by changing available irradiance. It is shown that hybrid energy storage systems with the associated cascade control help mitigate majority of the solar-induced power fluctuations.
