Reactive Power Compensation and Optimization of Integrated Grid Tied Cascaded Hybrid System
Cascaded multilevel converter structure can be fascinating for high-power solar photovoltaic (PV) systems due to its interchangeability, extensible, and dispensable maximum power point tracking (MPPT). Though, the power divergence in cascaded unitary PV transmute modules can cause unstable voltage and system operation. This paper highlights the concern, inspects the consequences of reactive power compensation and optimization on system security and power characteristics, and suggests synchronized active and reactive power distribution at the grid to diminish this instability. Also a wind energy system is connected parallel to the PV system to increase the system’s reliability. Additionally, an expansive control system with the reactive power compensation algorithm (RPCA) is suggested to acquire intense voltage regulation and competent power distribution.
