Microgrid design and operation for sensible loads: Lacor hospital case study in Uganda

This study aims to provide a comprehensive review about the configurations, operation, and integration of multiple energy sources for microgrid (MG) system. The applications of renewable and non-renewable energy sources have been discussed and analysed. Similarly, the several control strategies, protection schemes, and communication networks used for MG have been defined to provide a unique and distinct perspective for an optimal and real-time project. During the review analysis, different used software tools and techniques were observed and applied broadly. However, the most frequently used software and technique are hybrid optimization model for electric renewables (HOMER) Pro and particle swarm optimization algorithm. Additionally, the total global installed capacity for renewable sources is enhanced up to 2588 GW, including 627 GW of PV source, along with the global investment of USD 316.7 Billion on clean energy sources. Furthermore, the least levelized cost of energy for on-grid and off-grid hybrid systems using HOMER Pro was found as $0.072 and $0.145/kWh, respectively. Finally, the work has provided thorough study and future directions about MGs to assist engineers and researchers for their upcoming prospects in the field of renewable energy.

“…MGs are powered by micro-sources, which could be comprised of renewable sources such as wind turbines and solar panels, or non-renewables such as diesel generators and storge systems such as batteries, to collectively meet a system load. Many systems have been considered for loads including EV charging stations [1], hospitals [2], and forward operating bases (FOBs) for military applications [3]. [1] and [2] consider stationary, grid-connected architectures, while [3] considers a stationary, islanded architecture for the MG.…”

Meanwhile, [2] takes a data-driven approach, much of it used to design the MG, which is not the focus here.

The operation of microgrids (MGs) has garnered much attention in recent years due to their potential for leveraging renewable and non-renewable energy sources in a well-integrated system. One MG configuration which has not been extensively studied is the islanded vehicle-borne MG (VBMG). Optimizing the operation of any MG is important to ensure power security, resilience, and cost. The main factor considered in this paper is an operational condition in which additional fuel supply cannot reach an islanded VBMG. This paper discusses the optimal operation a VBMG while maximizing the amount of time given finite fuel constraints. The result can be key to ensuring successful power supply for critical tasks in applications such as disaster rescue and recovery, mobile medical services, and military applications.

“…In fact, in microgrids that use PV power as a major energy supply source, there are many cases in which a diesel generator is adopted as a spare power supply source to handle the customer load [17][18][19][20][21][22][23][24]. Recently, there are many microgrids that use a fuel cell as a spare power supply instead of a diesel generator due to environmental issues [25][26][27][28][29].…”

Capacity Design and Cost Analysis of Converged Renewable Energy Resources by Considering Base Load Conditions in Residential and Industrial Areas

In this paper, a design technique for constructing a renewable-energy-based power system based on a customer’s power load is proposed. The proposed design technique adopts a second renewable energy power source in charge of the base load and is an improved method of the referenced studies with one type of renewable energy power source. In this proposed method, fuel cells are adopted as the base power source, and PV (photovoltaic) power generation and an ESS (energy storage system) are adopted as the power generation sources that supply the middle-load and peak-load power. When the fuel cell is applied as a base power source through the method designed in this study, a cost reduction of approximately 30.03% is expected, compared to a system that does not use a base power source. In addition, the criteria for securing a system’s power supply stability and the economics when fuel cells are adopted are analyzed in terms of the system’s installation cost.
