Abstract:

This paper proposes a Lyapunov based approach to design a controller in order to enhance grid stability and inertia in microgrids (MGs). This strategy is applied to Distributed Generators (DGs) which are integrated to Energy Storage System (ESS). The proposed strategy uses a simple structure to enhance the grid inertia and to damp out the power oscillations. It is to some extent analogous to that of a synchronous generator (SG) which is called a Virtual Synchronous Generator (VSG). The robustness of the proposed controller is also verified based on a time domain mathematical proof. The proposed controller effectively operates based on local information, so that there is no need for communication links. Finally, simulation results show that the transient response of the grid frequency has been improved on account of enhancing the inertia of the main grid.
