GI primarily based Management Scheme for Single Stage Grid Interfaced SECS for Power Quality Improvement

ABSTRACT:

This paper presents an improved generalized integrator (GI)-based control with a frequency locked loop for multifunctional three-phase single-stage grid interfaced solar energy conversion system for power quality enhancement of the distribution network beneath abnormal grid conditions. The perturb and observe-based mostly most power purpose tracking technique is utilized to get peak power from solar photovoltaic array beneath varying atmospheric conditions. This management scheme provides unity power issue operation, load balancing, harmonics mitigation, and reactive power compensation. The improved GI management algorithm has a plus of higher dc offset and harmonics rejection capabilities as compared to a standard second-order GI algorithm. To substantiate the control scheme, tests are performed on a paradigm in the analysis laboratory for manifold operating conditions. Take a look at results show the satisfactory behavior below steady state and dynamic operating scenario like unbalanced load, solar irradiations variation, voltage sag, and swell and distorted voltage grid. The total harmonic distortions of the grid voltages–currents are achieved within constraints of grid code compliance of an IEEE 519 and 1564 standards.
