In this paper, a variable step size filtered X-least mean fourth (FX-LMF) algorithm is proposed for a single-stage three-phase grid tied solar energy conversion system with active shunt filter capabilities. It consists of a SPV (Solar Photovoltaic) array, a voltage source converter, a three-phase grid and connected linear and nonlinear loads. The proposed algorithm helps in faster convergence and...
This paper proposes an adaptive modified least mean fourth (MLMF) control scheme with perturb and observe (P&O) technique for a voltage source converter (VSC) connected to solar photovoltaic array (SPV), three single-phase non-linear loads in a three-phase, 4-wire system with DSTATCOM (Distributed Static Compensator) capabilities. The adaptive control scheme based on MLMF shows low mean square...
This paper proposes an improved proportionate normalized least mean square (i-PNLMS) control algorithm for a DSTATCOM (Distribution Static Compensator) in a system constituted by a nonlinear load fed from a distorted grid. This algorithm helps in achieving the desired grid currents easily and efficiently, and it shows an inherent tendency to adapt to the system's requirements. The obtained THD (Total...
In this paper, a second-order Volterra filter is used in association with Lyapunov's stability theory to generate the reference currents for a SPV-DSTATCOM (solar photovoltaic-distribution static compensator) system in the distribution system. The SPV-DSTATCOM system is integrated to the grid to compensate a nonlinear load while supplying SPV active power to the grid. The system is implemented on...
