Abstract
The power system is dominated by the renewable energy resources since last two decades. The main cause behind this enormous deployment of RES is to combat the global warming and to decrease dependency on fossil fuels. Wind energy is one of the abundant available sources of energy throughout the world. However, the huge deployment of wind energy in the power system cause vulnerability to the system. The main cause is the lack of system inertia in RES which cannot effectively respond during the power imbalance condition. To counter this effect, the virtual synchronous generators are deployed in the RES based power system. The VSG mimics the synchronous generator features and therefore it possesses the ability to provide the inertial support to system. In this paper, a wind base multiple VSG system is proposed to counter the frequency irregularities of the system. Furthermore, a comparison with classical droop control is done based on load variation. Moreover, the genetic algorithm is used to optimize the values of damping and inertia of the VSG. The performance of the proposed system is validated in MATLAB/Simulink 2019.
Highlights
The recent ecological changes and natural disasters around the globe and the rapid growth of population, has forced the human kind to discover new resources for power generation
virtual synchronous generator (VSG) is defined as a control scheme based on inverters that bears the features of an SG
In this paper a wind based multiple VSG system is studied to analyze the frequency stability of the system
Summary
The recent ecological changes and natural disasters (i.e. flood and pandemic) around the globe and the rapid growth of population, has forced the human kind to discover new resources for power generation. According to the Paris Accord, the largest economies are compelled to produce/generate more clean and green power, in order to decrease the global warming issues. For this reason, China has been transforming its electric power generation from fossil fuel-based power plants to renewable generation. The common RESs explored throughout the world are solar and wind besides hydro power. The main problem in the RESs is the lack of inertia They cannot contribute to the system power imbalance. The above authors either didn’t considered the WTS or the wind control parameters optimization for this reason a wind-based VSG scheme is studied in this paper. The simulation and results are presented in part IV, and conclusion is drawn in part V
