Abstract: The use of electric energy is, in developed countries around the world, a natural part of life. It is used everywhere for living, work and travelling, at any residence, commercial building, industry and so on. The number of electrical devices connected to the power system, during the century, has increased enormously, with the main increase having been during the last 20 – 25 years. The total power demand has also increased but not at the same rate as the number of devices connected. This is due to more power efficient equipment being used, both for new devices and older replaced devices. There are differences for different voltage levels and of course a large variation among different countries. Due to complexity of power system combined with other factors such as increasing susceptibility of equipment. With electricity demand growing, low power quality is on the rise & becoming notoriously difficult to remedy [1]. Distribution system needs to be protected against voltage sags, dips & swells that adversely affect the reliability & quality of power supply at the utility end. The Dynamic voltage restorer (DVR), which has been utilized in optimized way so as to improve performance, has been put under new technique of sag detection. The applications of Fuzzy logic controller have taken new dimension in various fields. In this paper, the essentials of control scheme with immediate voltage generation to regulate the unbalance voltage phase in three phase system and a tested method to improve the reliability within the distribution system is presented. The 13kV distribution system is having a three phase fault which controlled by non-linear techniques and their performance levels are compared. The capability of DVR is demonstrated using MATLAB/SIMULINK simulation models. This paper emphasizes the importance of DVR application for better power quality, by comparing the mitigated voltage and current THD values among PID, Fuzzy, PID-Fuzzy have been compared on account of the amount of compensation being injected into the system under voltage sag condition for non-linear loads.

Abstract: Power plays a vital role for a developing country like Bangladesh. Like the rest of the countries of the world, the demand of power is rising day by day in our country. But Bangladesh has been facing electricity shortage for many years. In our country, a major portion of total population still does not have the access to electricity. For becoming a developed country, Bangladesh has to overcome the problem of power crisis. Renewable energy can be a great source to solve this problem. Already some government and non-government organization are working on renewable sources like solar energy, bioenergy, wind energy, etc. In this paper we mainly focused to develop and implement microgrid system with CSP-biogas combined power plant for providing electricity in rural and remote areas of Bangladesh
