Abstract
In renewable energy sources the contribution of wind energy is more and essential to meet the
energy requirement in world. Before the development of power electronics switches the
maintenance of power quality and grid code requirements are very difficult to mitigate power
quality issues such as unbalanced voltages (sag and swell), LVRT, Frequency deviations and real
power and reactive power maintenance(absorption and compensation). In recent year’s
development of power electronics switches, these issues are solving by implementation of different
voltage restorer. This paper describes the principle of compensating voltage in power system
network by series compensation in coordination with Dynamic Voltage Restorer (DVR) and
Superconducting Magnetic Energy Storage (SMES) also analyse the response of Static synchronous
series Compensator (SSSC) based on SMES by using simple PI controller. Normally series
compensation is responsible to compensate power in unbalanced grid lines. There are many types
of series compensation devices such as voltage restorer, SSSC and TCSC etc. These two series
compensation methods are protects consumer loads from grid voltage fluctuations. This work is
suitable for variable speed grid connected wind energy conversion system. The improvement of
response time, reduction of controller complexity and voltage sag mitigation and LVRT
improvement have been simulated and analysed by MATLAB – Simulink.
