A review on distributed generation allocation and planning in deregulated electricity market

Currently, distributed generation (DG) based on conventional energy sources and renewable energy sources (RESs) have played a vital role throughout the world. Energy policies are promoting distributed energy resources such as energy efficiency, increasing the number of DG installations and RESs planning. It can be observed that the load growth rates of countries are rapidly increasing. However, uncoordinated management of these alternative energy sources can put a severe stress on the power grid. To overcome from this problem, DGs are the best options for managing the need of energy. In this work, the robustness, sustainability and reliability of DG has been discussed with various aspects including different contingency scenario. Contingency analysis of a power system is a major action in power system planning and operation. This review covers the recent works done in the area of integration of DGs with various scenarios in electrical power systems. The main objective of this work is to study how to achieve a better integration of flexible demand as demand response, demand side management (DSM) with DGs and make the grid proficient. It then reviews the key results in this field and some of the interesting research challenges can be addressed are also acknowledged.
