“…In other hand, steady and reliable performance in a large-scale transmission system does not necessarily mean the same performance can be achieved in a geographically small distribution system, as the local network can lose almost all PV power support in the area due to cloud coverage within a short period [21]. Such a system is important and needs to be examined thoroughly, but currently few detailed literatures are available on this issue.…”

Voltage stability analysis of power distribution systems with high photovoltaic (PV) penetration is a challenging problem due to the stochastic generation of a solar power system. Voltage stability is an important benchmark for defining PV’s penetration level in active distribution networks considering loading capacity. The massive integration of PV power units, the effect of distribution system characteristics, like high ratio of R/X, and the reported collapses in power networks come up in serious studies that investigate their impact and upcoming problems on distribution networks. Therefore, this paper proposes analytical voltage stability and it is implemented on IEEE 34 nodes radial distribution systems with 24.9 kV and 4.16 kV voltage levels. In this regard, in addition to given properties in stability and power loss analysis, a penetration coefficient for PVs is considered. Simulation results prove that the applied method can illustrate the positive and negative effects of PV in distribution networks.

Research Insights and Knowledge Headways for Developing Remote, Off-Grid Microgrids in Developing Countries

et al. 2019

Recent reports from international energy agencies indicate that more than a billion of the population in the world is deprived of basic electricity provisions, confined mainly to the remote communities of developing nations. Microgrids are promoted as a potential technology for electricity provisions to off-grid rural communities, but have failed to reach their value proposition in the context of rural electrification access. In view of the rampant rural electrification issues, the objective of this paper is to furnish an understanding of, and advance the knowledge into, methods to facilitate the design and development of microgrid systems for remote communities in developing countries. The methodology involves an integrative review process of an annotated bibliography to summarise past empirical or theoretical literature. As such, this research is based on evaluation attributes, and identifies the challenges and barriers for remote microgrids through an analysis of 19 case studies. The paper concludes by proposing key aspects that need to be considered for developing a framework to improve the sustainability of electricity provisions for off-grid rural communities in developing countries.

“…In contrast, electric machines need heavy and bulky batteries because of the low energy density of current batteries [22]. In addition, the electric power supply needed to recharge the batteries may be restricted to a few hours [23] and require a significant amount of time. Consequently, electrically powered machines are currently restricted to specific applications [24,25].…”

Biomass-fueled engines are a promising way to reduce the consumption of and dependence on fossil fuels. To create a working prototype, a detailed study of the thermodynamic cycle was developed. The dead volume was revealed to be the most limiting parameter for the engine efficiency. The cycle efficiency is reduced from 51.8% to 30.5% for the given example. The engine needs to be properly designed to minimize energy losses. In addition, the optimal compression ratio of the cycle is very low (about 3.5), losing energy in the exhaust gases and contributing to an inefficient engine. However, using a turbocharger can improve the cycle efficiency, combining the basic cycle with a Brayton cycle. Moreover, a two-stroke engine design is recommended for biomass-fueled engines. It allows minimization of the dead volume, is less sensitive to dirt, and avoids gas exchange with the combustion chamber during scavenging. Finally, the combustion chamber of the initial prototype was redesigned, based on the aforementioned improvements and allowing the successful start-up of the engine. This work demonstrates that biomass is a viable alternative to fossil fuels in applications where internal combustion engines are required.
