“…In addition, with the development of computer technology, more and more scholars have verified the effectiveness and reliability of hydrogen storage systems in wind-solar power generation through modeling and simulation [13][14][15][16][17][18][19]. Other scholars have designed the scheme on hydrogen storage of wind-solar power generation to optimize the system [20][21][22][23][24]. Hydrogen storage can provide frequency regulation and rotation reserve to effectively maintain the balance of grid generation and load [25].…”

To address the severity of the wind and light abandonment problem and the economics of hydrogen energy production and operation, this paper explores the problem of multi-cycle resource allocation optimization of hydrogen storage systems for coal–wind–solar power generation. In view of the seriousness of the problem of abandoning wind and photovoltaic power and the economy of hydrogen production and operation, the node selection and scale setting issues for hydrogen production and storage, as well as decision-making problems such as the capacity of new transmission lines and new pipelines and route planning, are studied. This research takes the satisfaction of energy supply as the basic constraint and constructs a multi-cycle resource allocation optimization model for an integrated energy system, aiming to achieve the maximum benefit of the whole system. Using data from Inner Mongolia, where wind abandonment and power limitation are severe, and Beijing and Shanxi provinces, where hydrogen demand is high, this paper analyzes the benefits of the hydrogen storage system for coal–wind–solar power generation, and explores the impact of national subsidy policies and technological advances on system economics.

“…LPSP can be defined as the ratio of supply energy shortage to the total BS demand for a given period that ranges from zero to one. However, LPSP can also be designated as the loss of load probability (LOLP), load coverage rate (LCR), loss of power probability (LOPP) in some literature [57,58]. Note that a higher value of LPSP signifies lower system reliability.…”

With the proliferation of cellular networks, the ubiquitous availability of new-generation multimedia devices, and their wide-ranging data applications, telecom network operators are increasingly deploying the number of cellular base stations (BSs) to deal with unprecedented service demand. The rapid and radical deployment of the cellular network significantly exerts energy consumption and carbon footprints to the atmosphere. The ultimate objective of this work is to develop a sustainable and environmentally-friendly cellular infrastructure through compelling utilization of the locally available renewable energy sources (RES) namely solar photovoltaic (PV), wind turbine (WT), and biomass generator (BG). This article addresses the key challenges of envisioning the hybrid solar PV/WT/BG powered macro BSs in Bangladesh considering the dynamic profile of the RES and traffic intensity in the tempo-spatial domain. The optimal system architecture and technical criteria of the proposed system are critically evaluated with the help of HOMER optimization software for both on-grid and off-grid conditions to downsize the electricity generation cost and waste outflows while ensuring the desired quality of experience (QoE) over 20 years duration. Besides, the green energy-sharing mechanism under the off-grid condition and the grid-tied condition has been critically analyzed for optimal use of green energy. Moreover, the heuristic algorithm of the load balancing technique among collocated BSs has been incorporated for elevating the throughput and energy efficiency (EE) as well. The spectral efficiency (SE), energy efficiency, and outage probability performance of the contemplated wireless network are substantially examined using Matlab based Monte–Carlo simulation under a wide range of network configurations. Simulation results reveal that the proper load balancing technique pledges zero outage probability with expected system performance whereas energy cooperation policy offers an attractive solution for developing green mobile communications employing better utilization of renewable energy under the proposed hybrid solar PV/WT/BG scheme.

The use of hydrogen as a fuel carries major environmental advantages because there are a number of ways of producing it by low-carbon methods. When electrolysis is used, additional benefits are obtained by flexible operation that offers the opportunity to reduce the cost of hydrogen production by absorbing electricity during off-peak hours, and stopping operation during peak hours. This can also act as a tool in support of balancing electrical systems. In this research, off-peak electricity is used to produce hydrogen via electrolysis, which is sold as a fuel at six garage forecourts in Darna, a small city on the east coast of Libya. In addition to the six forecourt electrolysers, a centralised electrolyser plant will be included in the system to consume the surplus energy and to satisfy any deficiency in hydrogen production at the forecourt. The capital cost of both forecourt and centralised electrolyser systems, plus fixed costs, were financed by bank loans at a 5% rate of interest over seven years. A MATLAB model with optimisation tools was used to formulate this problem. This research shows that forecourt hydrogen production at off-peak times (and without the centralised electrolyser) can satisfy nearly 53.93% of the fuel demand. This represents 59.82% of the total surplus renewable energy. The average hydrogen sale price at the forecourts is between £10.82-11.71/kg. After adding the centralised electrolyser, nearly 78.83 % of the total surplus power was absorbed and the average hydrogen selling prices were between £15.04-19.80/kg The centralised electrolyser can meet 43%, 49%, 50%, 42%, 57% and 53% of the deficit in consumption for stations 1, 2, 3, 4, 5 and 6, respectively.
