Micro-grid, which coordinates distributed energy resources in a decentralized way, is a promising approach to allow distributed energy resources to provide full benefits while reducing the control burden on the grid. By exploiting the concept of cyber-physical system (CPS), prediction can be easily incorporated into micro-grid, which helps the micro-grid work more effectively and safely. In such a case, in this paper, based on CPS, we propose a novel micro-grid model, within the framework of which, a more explicit wind-solar complementary power system is presented. Moreover, we show how the closed-loop control is implemented in the proposed model which is of benefit to the design of micro-grid.

<span>The growing demand for power that needs to be remotely transported creates a fast and effective solution of Distributed Energy Resources (DERs) integration. Distributed Energy Resources (DERs) can lessen the electrical and physical distance between load loss and generator, transmission and distribution, and the level of carbon emissions. Such challenges can be overcome by using microgrids, which combine various types of DERs without interrupting the grid operation, allowing the power system to detect and control the errors more efficiently, allowing the shedding load and automatic switching through control algorithms so that blackouts and power restoration times are shortened, enabling either a relevant grid or islanded mode operation, and improving system reliability and flexibility via DERs. This work includes modelling of hybrid AC micro-grid as well as presenting an efficient control technique for micro-grid. In the present work the performance of hybrid AC microgrid system is analyzed in the islanded mode. Photovoltaic system and fuel cell stack are used for the development of microgrid. It also includes microgrid control objectives and the most common problems encountered and their solutions. The employed control technique is able to control the output voltage at a desired and standard value. The control strategies of the hybrid AC microgrid are simulated in MATLAB/SIMULINK.</span>

A microgrid is a set of loads that are connected with each other and distributed energy resources within distinctly designate electrical boundary in such a way, it behaves as a one unit in regard to the grid. A micro grid associated with distributed energy resources (DER) has proved alternate sources of electricity rather than the fossil fuels likecoal. The consequential comfort associated with microgrids has paved the way to extend their perforation in a network of electrical components. There are many challenges and issues in integrating the micro grid to the utility grid. Research activities are in progress to solve the issues like design of a microgrid, control techniques and operating modes such as grid connected or islanded mode. This paper extends an exploration of issues concerning microgrids and furnishes the details of solutions suggested by researchers in areas of microgrids, including microgrid architecture, operation and control, DER, microgrid controllers, converters, energy management, protection and challenges which are yet to be addressed.

Micro grid comprises of various Distributed Energy Resources, Battery Energy Storage System (BESS) and various loads that can be connected to a grid or can be operated in an isolated mode. In this paper, micro grid comprises of a Diesel Generator set, wind turbine generator, Battery Energy Storage System (BESS) to feed a critical load in an isolated location. The intermittent energy from wind power is stored in BESS and a Centralized micro controller program is used to schedule the operation of Diesel Generator and BESS to provide an uninterrupted power supply to the critical load. The communication link between the microcontroller and Distribution Energy Resources will be a satellite link (GPRS/3G/4G/5G) or optical fibre cable. The main objective of this work is to reduce the usage of diesel generator output and utilizing the renewable energy in place of it to its maximum capacity. Meanwhile by proper scheduling, continuous working of BESS is ensured within its SOC limits. In this work, MATLAB simulation is used to simulate the load sharing among Diesel Generator and BESS. A hardware prototype is designed in proteus software and the hardware prototype is fabricated to verify the simulation results.
