Abstract:

Power can be generated from conventional as well as non-conventional sources. Power can be accepted from any type of source. With the increasing share of generating resources adding up in distribution side, the traditional frontier that is separating all the three parts (generation, transmission and distribution) of power system are vanishing rapidly. As the grid is transforming to microgrid and smart grid, the consumers are now termed as “prosumers”. The grid that is initially designed for one-way power flow is now experiencing two-way flow of power. As the energy storage cost is declining, it gives rise to new debate for the power system intellectualist whether to invest in conventional grid model (generation + transmission + distribution) or to invest in storage model (distributed generation + distribution + storage) With evolution of Microgrid and Smartgrid concept, power system is advancing to a new era of digitalized power system. With the digitalization of power system there comes various pros and cons in terms of technical as well as economic feasibility. Thus, requires new researches in this modern field.

Introduction: Energy can be generated from both conventional as well as non-conventional sources of energy. As the conventional sources are dependent on the fossil fuel they will be lasted for next few decades. Imagine the world without power and that too in the 21st century, everything will be at halt whether industries, transportation, food manufacturing as well as home appliances. Day by day power is becoming an important aspect of our life. The everlasting energy demand, along with environmental concerns and emerging of private players as well as competition has attracted interest in large deployment of nonconventional sources(NCS). There is a more severe drawback of reliability, power quality, transmission & distribution losses (Technical and Non-technical losses), efficiency as well as they are pecuniary, not sound when we are considering them on a large scale such as the Central grid. With increasing demand, it necessitates small grids which can effectuate the need of not just locality but also to the vicinity and which are not only reliable but lucrative as well. We require such small-scale grids which can fulfill the power requirements of remote areas without the huge investment in transmission lines. The Microgrid concept can be used to integrate the mix of NCS. The Microgrid system is a small power supply system that consists of loads and distributed energy resources (DER), such as renewable energy (RE) sources, co-generation, combined heat and power (CHP) generation, fuel cell and energy storage systems. They have an edge of higher flexibility, reliability, efficiency of operation, economic, cost effective, fuel efficient and bidirectional power flow between utility grid and the Microgrid if operated under the grid connected mode of operation. The Microgrids can be categorized as AC Microgrid and DC Microgrid. Microgrids can reinforce grid elasticity and helpful in reducing grid disturbances. It also functions as a grid resource for faster system response and recovery. The concept of Microgrid has grown out of this desire for true interconnection of the distribution system. It is predicted that this Microgrid concept will prove to be a perfect solution to rural electrification projects. It is very well useful in commercial and industrial sector requiring improved reliability and power quality as there is a shortage of electricity in India. However, factors like reactive power compensation, power quality, and controllability are the key factors which should be taken in mind. The DC Microgrid is the best solution to these types of problem. However, this will not only make the source of power reliable but on long-term analysis, it is cheaper. The microgrid concept is very helpful for small communities who want to take control of their energy usage and reduce their carbon emission by using an innovating way of generating and harnessing energy. In this way, the community can lead towards a smarter way of harnessing power as well as contribute towards the green environment.
