Performance Improvement and Evaluation of Grid connected Hybrid power system

This paper evaluates the performance of a grid connected hybrid system. The hybrid system consists of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC). Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. The objective of the paper is to coordinate the two control modes and determine the ref...

Power Management in a Utility Connected Micro-Grid with Multiple Renewable Energy Sources

As an efficient alternative to fossil fuels, renewable energy sources have attained great attention due to their sustainable, cost-effective, and environmentally friendly characteristic. However, as a deficiency, renewable energy sources have low reliability because of their non-deterministic and stochastic generation pattern. The use of hybrid renewable generation systems along with the storag...

Detection of Power Quality Disturbances in Micro Grid Connected Power System

Micro Grid is a contracted distributed AC or DC network. Micro Grid resources are connected to the distributed linear as well as nonlinear loads through power electronics converter to provide an efficient, more reliable and quality power to the distributed loads with reduced co2 emission. Consequently makes full use of low cost generation resources and reduce waste. Interconnected Mode in the M...

Optimal Operation of Doubly-fed Induction Generator used in a Grid-Connected Wind Power System

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...
