“…In recent years, many research studies on P2H2P systems have dealt with the energy management systems, controller functions, technical challenges of RESS components, and economic analysis. Studies such as Giorgio Caua et al 2014 [19], L. Valverde et al 2016 [20], Mauricio Higuita Cano 2017 [21] and Yanfeng Liu et al 2018 [11] examined the optimal scheduling of the RESS components to maximize the benefit of the RE and minimize the investment cost. These research studies have concluded that an energy management strategy is essential for the optimal utilisation of the P2H2P systems as well as the optimization of the RESS.…”

“…The P2H2P systems comprise three main components; the electrolyser, hydrogen storage and fuel cell (FC), as illustrated in Figure 1. ηRound-trip = ηElectrolyser * ηStorage * ηFC (1) The energy management strategy, i.e., the controller's operating algorithm, has an enormous effect on the optimal utilisation of the P2H/P2H2P systems, i.e., electrolysers and fuel cells operating hours, the number of starts/stops cycles and the components' degrading rate [50,51].…”

“…The three water electrolysis technologies most mentioned in the literature are [35,48,62]: The PEM technology electrolyser was used in this research study for its merits of maturity and suitability for the acceptable efficiency in partial and full load performing, as well as the fast response to the input/output power fluctuation [35,48,63]. However, there are some challenges in utilising and sizing the electrolyser, such as the H 2 production capacity, excess energy availability and the number of start/stop cycles (up to 10,000 cycles before ultimate degradation [50]). Moreover, the maturity in electrolysis technologies (electrolysers), has made the P2H systems a promising gateway towards the hydrogen economy era [5,10,39,48,[64][65][66][67].…”

Stand-Alone Microgrid with 100% Renewable Energy: A Case Study with Hybrid Solar PV-Battery-Hydrogen

A 100% renewable energy-based stand-alone microgrid system can be developed by robust energy storage systems to stabilize the variable and intermittent renewable energy resources. Hydrogen as an energy carrier and energy storage medium has gained enormous interest globally in recent years. Its use in stand-alone or off-grid microgrids for both the urban and rural communities has commenced recently in some locations. Therefore, this research evaluates the techno-economic feasibility of renewable energy-based systems using hydrogen as energy storage for a stand-alone/off-grid microgrid. Three case scenarios in a microgrid environment were identified and investigated in order to select an optimum solution for a remote community by considering the energy balance and techno-economic optimization. The "HOMER Pro" energy modelling and simulating software was used to compare the energy balance, economics and environmental impact amongst the proposed scenarios. The simulation results showed that the hydrogen-battery hybrid energy storage system is the most cost-effective scenario, though all developed scenarios are technically possible and economically comparable in the long run, while each has different merits and challenges. It has been shown that the proposed hybrid energy systems have significant potentialities in electrifying remote communities with low energy generation costs, as well as a contribution to the reduction of their carbon footprint and to ameliorating the energy crisis to achieve a sustainable future.A modern microgrid is an integrated energy system consisting of localised grouping of distributed electricity generation with storage and multiple electrical loads [11,12]. It can be controlled as one entity or grid, either standalone, completely separate from, or connected to, the existing utility grid [13]. The development of the microgrid has been largely dominated by energy demand-side management, RE penetration and its integration into the utility grid [14,15]. In cases where it is not possible to connect the microgrid to the utility grid for any reason such as the remote or isolated location, a stand-alone microgrid (SAM) is an answer to the power supply challenges [16]. The authors of this research envisioned that the SAM is a good starting point to transit from the classic trend of fossil-fuelled powered systems to 100% RE powered systems.The SAM is a low-voltage power system that supplies a specific localised area [17]. It comprises local power generation systems with load demands, that can operate in islanded mode or off-grid [18,19].In the transition to a 100% RE SAM system, hybrid distributed (decentralized) or centralized energy generation and storage systems are used to meet the energy need [18]. The SAM is presented as a viable and effective solution to the utilisation of renewable energy resources (RER), by minimizing the problems associated with variability and intermittency of the renewables [16]. The main challenge in a SAM system is the optimal sizing of the system components to make the...

Wind resource characteristics in a mountain wind farm is more complicated and changeable than that in a flat wind farm due to the influence of complex mountain terrain-topography on air flow. Although there have been a large number of investigations on wind resource characteristics, the local wind resource characteristics in a mountain wind farm are still a lack. To fill this knowledge gap, high-resolution wind data are extracted for investigating from multiple-unit SCADA data, that is, wind data are collected from four selected wind turbines with SCADA system, which means wind data are from four different locations. For each location, more than thirty million sets of wind data are extracted for investigation in 2015. Then, several kinds of probability density functions (PDFs) are compared, and one-dimensional and multidimensional kernel density estimation method is selected for the investigation of the frequency distribution. Data preprocessing methods of both wind speed and wind direction are also presented. Finally, the results of this investigation reveal the specific change characteristics of wind speed and wind direction in the investigated mountain wind farm. Yearly mean wind speeds for four different locations are 3.

Techno‐economic analysis of a stand‐alone photovoltaic system with three different storage systems for feeding isolated houses in south Algeria

et al. 2020

This paper presents a technical and economic simulation of a solar photovoltaic system with three different storage types. Battery lead‐acid, battery lithium‐ion, and hydrogen storage have been used to cover the consumption of houses in an isolated village in southwest Algeria. The main objective of this study is trying to use the roof of the houses to cover consumption by installing solar panels and build a room for electric equipment like inverter, battery, power system management, and so forth. The proposed hybrid system size is 50 photovoltaic panels with 7 kW electrolyzer and a tank of 6 kg for hydrogen storage. The hourly consumption of this houses was estimated during two seasons; season of low consumption (winter) and season of high consumption (summer). The results obtained from Hybrid Optimization Model for Electric Renewable PRO software have been validated using MATLAB/Simulink software. The results show that the best storage system is the hydrogen storage due to low excess energy with no unmet load, the results show also that the system that uses hydrogen storage is the most economic system compared to the other storage types (lead‐acid and lithium‐ion) due to low investment cost and long lifetime. This system costs 51 282€.
