Global Trends and Opportunities in Hybrid Microgrid Systems Using Renewable Energies

Abstract

Access to energy is related to the essential aspects of modern survival, impacting production processes, access to knowledge and economic development. The global energy demand grows every year, and remote areas without connection to central grids need viable and sustainable alternatives for generating, distributing and storing energy at the local level. This paper presents an analysis through academic research, patent publications, reports and government information to map global trends and identify the opportunities for hybrid systems for power generation in microgrids from renewable sources and with several modes of generation. The data showed recent exponentially rising technologies with a tendency to continue for the next few years. China leads in isolation followed by USA and India. Countries like Brazil and Mexico, despite favourable conditions, do not present local technological development nor are they seen as a market of interest. Technological and research routes point to improving storage processes. Photovoltaic energy source was most used and to lesser extent wind, biomass, bioethanol, biogas, biodiesel and biohydrogen. Most of the inventions were focused on creating and improving machines, equipment, and systems to operate and control, utilizing the Homer software, for example.

An Assessment of Solar Micro-Grid System in the Islands of Bangladesh for Sustainable Energy Access

“…In recent years, using renewable energy sources to solve the electricity problems of remote areas has become a hot research topic in renewable energy system applications [3]. The microgrid system has advantages, mainly for providing the decentralization of energy generation that, based on the electricity demand, can be used well in each location based on the topographical position and distribution of renewable resources [4].…”

Influence of Photovoltaic Systems on Power Quality Problems

“…The quality problems of electrical energy that can manifest due to the connection of PV systems are related to the characteristics of these systems in the generation process, which usually manifests itself in voltage and current imbalances, in addition, to a linear component in the waveform after the rectification process, which added to non-linear loads connected to the system, can cause harmonics, power factor displacements, and power quality problems at the point of connection with the network operator (NO) (de Cerqueira Lima e Penalva Santos et al, 2022;Girigoudar and Roald, 2020). This research work is intended to determine the behavior of the power system of a commercial installation with problems of quality of electrical energy, which are evidenced by having a higher than average energy consumption.…”
