Renewable energy generation system connected to micro grid and analysis of energy management: a critical review

Abstract

Renewable energy generations have been employed throughout the world in order to meet the increasing load demand. It is a pollution free and abundantly accessible. The generation cost has been reduced because of more research advancement. Photovoltaic (PV) can’t generate throughout the day due to weather condition. In order to maintain the continuity of power generation a hybrid renewable generation system (HRGS) concept has been considered in this research work. HRGS is an integration of more than one renewable energy which consists of PV, wind, solid oxide fuel cell (SOFC), an auxiliary unit (AU). AU is used as a backup generation which can generate power when all the renewable energy fails to generate. AU may be of diesel generator (DG) or super capacitor. This paper discusses the various parts of HRGS and its comparison. Furthermore, its impact of energy management so as to deliver the energy to the grid in a continuous and reliable manner. Therefore, a detail study of different component of HRGS & renewable energy has been highlighted which will be helpful for the new researchers for advancement of power generation and its control strategy of energy management connected to the grid.

Optimization of energy management in hybrid SOFC-based DC microgrid considering high efficiency and operating safety when external load power goes up

“…Thus, fuel starvation must be addressed during the external load power rises up. 12,13 The above issues have a direct impact on SOFC-based DC microgrids. In the past decades, great investigative efforts have been undertaken to solve these above problems.…”

A heuristic optimization approach for the scheduling home appliances

“…HEMS can be installed in homes to help with power management by communicating with utilities and home appliances, keeping track of energy use, and receiving information (such tariff pricing) to schedule the operation of home appliances and other equipment to consume less energy. This system can manage distributed energy resources and storage while also optimizing the operating schedules of home appliances [1]- [4].…”

Analysis of total harmonic distortion in single-phase single-stage grid-connected photovoltaic system

“…The conventional non-renewable sources will give effects on the environment such as carbon dioxide, carbon monoxide, sulphur dioxide, and many more [2]. Thus, the installation of renewable energy systems on medium and low-voltage distribution networks is gaining popularity [3]. The use of PV systems, which are safe, clean, highly reliable, and abundantly available from the sun's source of energy, has rapidly grown across the globe [4]- [6].…”
