Dynamic reactive power compensation equipment typically requires a fast response to output the necessary power. The term “dynamic time of power” is often used but has never been clearly defined. This paper summarizes calculations under different definitions and algorithms considers these in terms signal processing simulate analyze step response. subsequently focuses on widely instantaneous algo...

The photovoltaic (PV) system exhibits a nonlinear current-voltage (I-V) characteristic that its maximum power point (MPP) varies with solar insolation and temperature. In this paper, a maximum power point tracking (MPPT) method using fuzzy logic control (FLC) is presented. This method is based on the concept of perturbation and observation (P & O) algorithm to track the MPP. The two stage grid ...

This paper presents a review of DSTATCOM Topologies and power quality control Techniques. The used topologies are Three-phase Three-wire four-wire techniques Instantaneous reactive theory(IRP), Synchronous Reference Frame Theory(SRF), Model Predictive Control (MPC), Sliding mode control(SMC), Adaptive Neuro-fuzzy interface systems(ANFIS) Artificial intelligence based controllers. These to mitig...

Most of the pollution issues created in power systems are due to the non-linear characteristics and fast switching of power electronic equipment. Power quality issues are becoming stronger because sensitive equipment will be more sensitive for market competition reasons, equipment will continue polluting the system more and more due to cost increase caused by the built-in compensation and somet...

This work deals with the design, analysis and simulation of shunt active power filter SAPF, which compensate harmonic currents, and reactive power under balanced supply network. An optimal control theory for currents compensation based on particle swarm optimization is developed in this paper. The SAPF is connected in parallel with a nonlinear load which has caused current harmonics in industri...

This paper presents a single-phase inverter with multilevel topology adopted to interface photovoltaic systems with the electrical power grid, and at the same time, to eliminate harmonics currents and to compensate reactive power, operating as shunt active power filter. Multilevel inverters have been attracting increasing attention in the past few years as power converters of choice in high vol...

This paper deals with the implementation of cascade multilevel inverter-based STATCOM, which employs H-bridge inverter. The STATCOM system is modeled using the d-q transform, which calculates the instantaneous reactive power. In this paper, a power line conditioner using a cascade multilevel inverter is presented for voltage regulation, harmonic filtering and reactive power compensation (var). ...
