AC DYNAMIC LOAD CONTROL FROM SOLAR ENERGY BY USING PHASE-IN POSITION CONTROL TECHNIQUE

electrical engineering

This paper presents the design, control and simulation of multifunctional, two-stage, three- Phase SPV energy conversion system which have been carried out using an control algorithm based on ANF. The ANF has been used for extraction of fundamental part of load current. The reference grid currents are then estimated using all load currents, PV contribution and loss component of VSC, which are further used to generate the switching pulses for VSC. The performance of the system has been demonstrated for harmonics elimination, compensation of reactive power, load balancing and power factor correction. An InCA technique has been used for the electrical MPPT of SPV panels. The performance of the two-stage, three-phase grid-interfaced SPV energy system has been found satisfactory under different dynamics and steady state operating conditions. The THD of grid currents is found well under IEEE-519 standard. A wide range of simulation results has been shown to prove the feasibility of the control approach.
