![]() The comparative analysis is analyzed to check the effectiveness of the proposed hybrid control scheme with existing and adaptive control techniques in respect of power quality, better dc offset rejection, better FC and frequency extraction, and grid synchronization. ![]() MCCF is employed to separate the FC from the distorted grid voltages and eliminates the voltage harmonics during extremely polluted grid voltage condition. A reference current generation strategy is implemented to mitigate the current harmonics by extracting the fundamental constituents (FCs) from the nonlinear load currents. ![]() In this work Artificial Neural Network controller used to destroy the voltage and current harmonics in a grid-tied PV system. This project aims to improve the power quality level of a grid-tied PV distribution system using shunt active power filter (APF) along with adaptive current control technique. Grid-connected photovoltaic (PV) systems are increasingly attracting the attention of industry and academia as a means of providing an alternative to conventional fossil-fuel generation and pollution-free power. It also shows that a small resistance, inserted for less than one The analysis shows that SDBR can substantially improve the FRT performance of a FSWT wind farm. This is achieved by quasi-steady-state characterization and transient FRT stability simulations. This paper uses a representative wind farm model to study the beneficial effect of SDBR compared to dynamic RPC. The series dynamic braking resistor (SDBR) dissipates active power and boosts generator voltage, potentially displacing the need for pitch control and dynamic RPC. A novel alternative technology is proposed that inserts series resistance into the generation circuit. These present technologies can therefore be limiting, especially when connecting to smaller power systems. Dynamic RPC is constrained by its high capital cost. Blade pitching is constrained by the onerous mechanical loads imposed on a wind turbine during rapid power restoration. State-of-art techniques applied to meet grid requirements for FSWT wind farms are blade pitching and dynamic reactive power compensation (RPC). Fixed speed wind turbines (FSWTs) are a diminishing but significant sector in the fast-growing wind turbine (WT) market. Fault ride-through (FRT) is required for large wind farms in most power systems.
