“…This will be discussed under the subheadings of improvement in power grid energy efficiency, competitive cost of energy storage and renewable energy, and regional integration for energy trade. Improvement in power grid energy efficiency: Energy efficiency is an often-ignored catalyst for sustainable energy access and has received significant attention due to its capability to improve energy access with less generation-related emissions ( Babayomi et al., 2020 ). The electrical power grid comprises three main parts: generation, T & D, and the end-users.…”

“…Demand side management is the overall means of achieving energy management of the users' load. It includes energy efficiency, energy conservation, time of use, demand response, and spinning reserve ( Babayomi et al., 2020 ; Oluseyi et al., 2020 ). Incorporating a wide-scale energy efficiency program for energy users contributes to a more sustainable grid.…”

“…It is highly inevitable that the higher the electrification, the more poverty can be reduced, especially in developing countries [3]. Electrification projects are not only conducted in urban areas aiming for higher energy efficiency [4] [5] but also applied in rural areas [6] [7]. Thereof, a lot of microgrid projects have been initiated and conducted in both rural and urban areas [8].…”

Degradation of components and system failure within the microgrid system is deteriorating the performance of electrification. The aim of this study is to discuss the relationship and connections between issues resulting from degradation and deterioration in the microgrid system, in addition to introducing the prominent impacts which may eventually lead to the premature termination of the microgrid system. This study explored the microgrid degradation and deterioration issues within four microgrid sections: generation section, storage section, transmission section, and distribution section. Subsequently, this study analyzes, derives, and classifies all emerging issues into four types of prominent impacts. The degradation and deterioration invoked many component performance issues into four main damaging outcomes, namely (i) deteriorated transmission line yielded issues regarding expected energy not achieved; (ii) energy deficit and unpredicted blackout come after the depth of discharge (DOD) reduction and invoke a loss of power supply; (iii) a shorter battery life cycle, shorter transformer lifespan, and decreased DG lifetime concluded as a shorter microgrid life expectancy; and (iv) rapid microgridbroke down and the crash of the key component inadvertently fastened the time to failure and gave rise to the early failure of a microgrid system. It is envisaged that the discussion in this study can provide useful mapped information for the researcher, stakeholder, operator, and other parties for thoroughly addressing various degradation and deterioration issues and anticipating the early termination of the microgrid system.

“…Therefore, the impacts of DGs on the existing distribution system must be thoroughly investigated in order to ensure the stability and reliability of the system. The integration of DG into the distribution network has a great impact on the steadystate and transient behaviour of the network which depends on the DG capacity and penetration levels, type of generator, the method by which the generator is interfaced with the network and the location of the connected DG [3,4], just as in the case of capacitor and or phase measurement unit (PMU) placement. The steadystate behaviour of the network describes the healthiness of distribution network before and after the integration of the DG.…”

Integration of Distributed Generation (DG) on distribution networks has a positive impact which includes the following: low power losses, improved utility system reliability and voltage improvement at buses. A real distribution network is radial in which energy flow is unidirectional from generation to transmission and from distribution to the load. However, when a DG is connected to it, the power flow becomes bidirectional, and the protection setting of the network may be affected. Therefore, the aim of this research work is to investigate the impact of distributed generation DG on power system protection. The test distribution network is first subjected to load flow analysis to determine its healthiness with and without DG connection. The load flow results confirm that the integration of the DG into the distribution network reduces the active power load loss by 92.68% and improves voltage profiles at each bus of the network by 90.72%. Thereafter, the impact of DG on the protection setting of the existing test network was investigated. Integrating DGs to the network, from our result, shows an increase in the fault currents, which in turn caused false tripping, nuisance tripping, and blinding of protection relay compared with when DGs are not connected. The protection relays were reset at the point of common coupling (PCC) to prevent any abnormal tripping. This is the major contribution of the research work.
