The electrical characteristics of PV panel can be represented by an equivalent electric circuit model. Major challenge lies in the accurate estimation of PV model parameters. In this study, a new and efficient approach is proposed to estimate the seven-parameter PV electric circuit model. Estimation process is converted to an optimization problem where differential evolution is employed to identify...
This paper presents a novel robust control design approach for grid-connected voltage-source-inverter with uncertain grid-impedance. The proposed method is based on the fusion of intelligent and robust control theories. The controller is designed to achieve the highest convergence rate of the system for a certain uncertainty range. The control objective is to regulate the real and reactive power injected...
Photovoltaic (PV) panel can be represented by an equivalent electric circuit where the major problem with this PV model is the determination of the model parameters. In this paper, PV parameter estimation problem is converted to an optimization problem where Differential Evolution (DE) as an efficient optimizing technique is employed to estimate the model parameters at standard test condition (STC)...
This paper proposes a method based on differential evolution (DE) algorithm for the problem of optimal placement of phasor measurement units (PMUs) in an electric power network. The problem is to minimize the required number of PMUs and, at the same time, maximize the PMU measurement redundancy subject to the constraint of achieving full network observability. Network observability is assessed with...
This paper investigates the application of differential evolution (DE) algorithm for the problem of optimal placement of phasor measurement units (PMUs) in an electric power network. The problem is to determine the minimum number of PMUs and their respective locations to make the system observable. In order to cope with the continuous changes in the power system's topology, the optimization problem...
