“…Some additional sources and sinks are required to integrate the various sources in Microgrid to counterbalance the fluctuating nature of the solar. With fast development in renewable energy and Power electronics technology, cost reduction in energy storage and wider applications of the microgrid system, different control strategies and Demand management systems have been proposed for solar integration [6] [1].…”

The future electricity sources in India must be green energy, flexible, accessible and sustainable. The Educational Institutions are a back bone of any country, which are planning major role in development of nation. In India maximum Educational Institutions have only day scholars and maximum electrical energy demand in Institutions between 9.00 AM to 4.00PM. The government of India introduce many programs for green campus development across the country, under this program solar power plant will be setup for fulfil the electrical demand in day time. The educational institution will implement the Microgrid in ON-Grid mode for fulfil the electrical demand from solar PV Power Plant. In this paper we are studying the major challenges for microgrid implementation in Educational Institutions in India.

The increased penetration of Distributed Energy Resources (DER) is challenging the entire architecture of conventional electrical power system. Microgrid paradigm, featuring higher flexibility and reliability, becomes an attractive candidate for the future power grid. In this paper, an overview of microgrid configurations is given. Then, possible structure options and control methods of DER units are presented, which is followed by the descriptions of system controls and power management strategies for AC microgrids. Finally, future trends of microgrids are discussed pointing out how this concept can be a key to achieve a more intelligent and flexible power system.

“…Moreover, a number of AC-distributed resources are connected to the microgrid through a multi-stage conversion controller, which lowers the system efficiency to some extent [11][12][13][14][15]. As an alternative to an AC microgrid, a direct current (DC) distribution microgrid has several attractive features and is developed in [16,17].…”

A Coordinated Control for Photovoltaic Generators and Energy Storages in Low-Voltage AC/DC Hybrid Microgrids under Islanded Mode

Abstract:The increasing penetration of renewable generators can be a significant challenge due to the fluctuation of their power generation. Energy storage (ES) units are one solution to improve power supply quality and guarantee system stability. In this paper, a hybrid microgrid is built based on photovoltaic (PV) generator and ES; and coordinated control is proposed and developed to achieve power management in a decentralized manner. This control scheme contains three different droop strategies according to characteristics of PV and ES. First, the modified droop control is proposed for PV, which can take full utilization of renewable energy and avoid regulating output active power frequently. Second, to maintain the direct current (DC) bus voltage stability, a novel droop control incorporating a constant power band is presented for DC-side ES. Third, a cascade droop control is designed for alternating current (AC)-side ES. Thus, the ES lifetime is prolonged. Moreover, interlinking converters (ICs) provide a bridge between AC/DC buses in a hybrid microgrid. The power control of IC is enabled when the AC-or DC-side suffer from active power demand shortage. In particular, if the AC microgrid does not satisfy the reactive power demand, IC then acts as a static synchronous compensator (STATCOM). The effectiveness of the proposed strategies is verified by simulations.
