Abstract:

The frequency is stable in the conventional power system due to kinetic energy stored in the Synchronous Generators (SGs), which can inject sufficient power into the power system network for maintaining the power balance in the system. However, the inertia in the SG inhibits abrupt deviations in frequency and maintains stability. Distributed Generators (DGs) are static and there is no rotating part to store the kinetic energy, and the moment of inertia of the grid is decreased and affects the system stability greatly. A control scheme is applied to the inverter such that the inverter acts like a Virtual Synchronous Generator (VSG). The design of the VSG incorporates the droop characteristics, swing equation, and damping properties of SG. The work proposed here covers the modeling of VSG and operating in both islanding and also grid-connected mode. The simulation results show the effectiveness of the proposed controller.

I. Introduction

Non-renewable energy sources include fossil fuels like oil, coal and natural gas are the overall main source of energy. As it creates lots of pollution as well as depletes resources, the continuous usage of fossil fuels is overall accepted as unsustainable [1]. Therefore it is very important to find out another option and the environmentally friendly energy sources for decreasing the overconsumption of fossil fuels. Under the present environmental and economic situation, renewable energy sources (RESs), like solar energy or photovoltaics (PV) as well as wind energy will provide better solutions [2]. There is a lot of demand for the RESs for the development of the distribution system because of the advancement of the power electronics field as well as the increasing popularity of RESs in the past decades. The large penetration of RESs and the linear growth in the capacity of the inverter based distributed generator (DG) is introducing a huge change in the global electrical power system and network [3]. In the traditional power system, the SGs plays an important role. The SGs having the rotors, such that kinetic energy (KE) stored in the rotor. This KE and the damping characteristics of the traditional synchronous machine play a most crucial role in the stability of the system. In case of any disturbances or sudden changes occurring in generation or load, these SGs can inject KE which is stored in the rotor of the conventional synchronous machine.
