With the increased penetration of intermittent renewable energy sources (RESs) in future grids (FGs), balancing between supply and demand will become more dependent on demand response (DR) and energy storage. So far, FG feasibility studies, especially those claiming a long-term view, typically do not model the electrical network and/or the effect of DR. Thus, in this thesis, we first present a simulation platform for performance and stability assessment of FG scenarios.

Abstract:

The grid-connected photo-voltaic (PV) system is one of the most promising renewable energy solutions which offers many benefits to both the end user and the utility network and thus it has gained the popularity over the last few decades. However, due to the very nature of its invariability and weather dependencies, the large scale integration of this type of distributed generation has created challenges for the network operator while maintaining the quality of the power supply and also for reliable and safe operations of the grids. In this study, the behavioral impact of large scale PV system

Abstract:

Renewable energy is the alternative sources of electrical energy to fulfill energy shortage. micro grid allows to connect multiple renewable energy sources to it. Photovoltaic (PV) generation is one of the major renewable energy sources. PV generation systems directly connected to micro grid brings some problems like voltage deviation, current fluctuation etc. which brings instability into the system. Thus, a smooth micro grid connection with PV system is required. Here H∞ control method based on model matching technique has been adopted for our system. To extract maximum power from PV array,

This topology minimizes the number of switching devices used, thereby reducing power losses that arise from high frequency switching operations. The control strategy is implemented using a simple micro-controller that implements the proportional plus integral control. All the control loops are closed feedback loops hence minimizing error instantaneously and adjusting efficiently to system variations.
