This paper proposes a new hybrid active power filter, including voltage source converter (VSC) based active power filter and Thyristor Controllable LC Passive Filter (TCLC-HAPF) for eliminating harmonic load current components and compensating reactive power. This new structure which is based on the separation of high and low-frequency components of load current idea can reduce the drawbacks of...

The solar chimney power plant (SCPP) generates updraft wind through the green house effect. In this paper, the performances of two SCPP styles, that is, the conventional solar chimney power plant (CSCPP) and the sloped solar chimney power plant (SSCPP), are compared through a numerical simulation. A simplified Computational Fluid Dynamics (CFD) model is built to predict the performances of the ...

In this paper, a new non-isolated transformerless high step up Dc-Dc converter with low voltage stress on the active switch for solar energy application is proposed. The converter topology is simple, which makes the control scheme simple. In this converter, only one active switch is used which makes reducing the switching power loss. The voltage gain of the proposed converter is higher than the...

In this paper, hybrid particle swarm optimization and gravitational search algorithm is proposed to find the optimal solution for the optimal power flow problem including three wind farms connected to the isolated Adrar Algerian power system. In order to get the cost model, the economic problem is converted into a single objective function considering the fuel cost and cost of wind generation b...
