Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

Distribution grids evolve more and more to so called “Smart Grids” with a decentralized structure. New information and communication technologies (ICT) to manage these “Smart Grids” are necessary to integrate a high share of renewable energy systems. Due to a high number of system components the optimal operation and control of “Smart Grids” is highly complex which is why this paper uses the ap...

This paper present a control strategy for the operation of solar energy generation integrated with grid. Boost converter is used to achieve maximum power extraction from the available solar power. The buck converter and bi-directional converter connected with common dc bus, that dc bus connected different loads with constant dc voltage. The hysteresis current controller has implemented in inver...

Renewable energy sources are gradually being recognized as important options in supply side planning for microgrids. This paper focuses on the optimal design, planning, sizing and operation of a hybrid, renewable energy based microgrid with the goal of minimizing the lifecycle cost, while taking into account environmental emissions. Four different cases including a diesel-only, a fully renewabl...

Islanding detection is one of the essential features for photovoltaic grid-connected systems; detection performance is directly related to safe operation of the equipment. Summarize existing islanding detection, then an active method based on frequency – reactive power feedback islanding detection is proposed. Once an islanding condition occurs, the method introducing a load frequency reactive ...

A new development of Dual-MPPT algorithm for single-phase grid-connected photovoltaic generation systems under variation of irradiance is presented in this research. This method is extract the maximum available power from PV module by making them operates at the most efficient output and fastest transient response. In order to accelerate the tracking speed, an incremental conductance based inte...

In this project, a simple static var compensating scheme using a cascaded two-level inverter-based multilevel inverter is proposed. The topology consists of two standard two-level inverters connected in cascade through open-end windings of a three-phase transformer. The dc-link voltages of the inverters are regulated at different levels to obtain four-level operation. The simulation study is ca...

In the future, renewable energy sources will contribute a significant share if not the majority of our energy supply. Especially for the electricity sector this means a radical transformation from current practise. The current infrastructure will in part need to be adapted but in part also to be rebuilt. This reorganisation taking place during “operation” increases the difficulty of the task at...

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...
