“…The discharge current (A) versus capacity (Ah) characteristic of the Trojan L16P battery is demonestrated in Figure 5. The duration of the battery bank can supply without outside assistance affects its autonomy and may be estimated as follows [6] (10) where V nom is the nominal voltage of a single battery (V), Q nom is the nominal capacity of a single battery (Ah), the battery SOC min indicates the lower threshold limit of battery discharge [6].…”

Hydrogen has received tremendous global attention as an energy carrier and an energy storage system. Hydrogen carrier introduces a power to hydrogen (P2H), and power to hydrogen to power (P2H2P) facility to store the excess energy in renewable energy storage systems, with the facts of large-scale storage capacity, transportability, and multiple utilities. This work examines the techno-economic feasibility of hybrid solar photovoltaic (PV)/hydrogen/fuel cell-powered cellular base stations for developing green mobile communication to decrease environmental degradation and mitigate fossil-fuel crises. Extensive simulation is carried out using a hybrid optimization model for electric rnewables (HOMER) optimization tool to evaluate the optimal size, energy production, total production cost, per unit energy production cost, and emission of carbon footprints subject to different relevant system parameters. In addition, the throughput, and energy efficiency performance of the wireless network is critically evaluated with the help of MATLAB-based Monte-Carlo simulations taking multipath fading, system bandwidth, transmission power, and inter-cell interference (ICI) into consideration. Results show that a more stable and reliable green solution for the telecommunications sector will be the macro cellular basis stations driven by the recommended hybrid supply system. The hybrid supply system has around 17% surplus electricity and 48.1 h backup capacity that increases the system reliability by maintaining a better quality of service (QoS). To end, the outcomes of the suggested system are compared with the other supply scheme and the previously published research work for justifying the validity of the proposed system.

“…The pdf for each hour is different because the solar irradiance is time-and weather-dependent. With these pdf and from the specification of the PV module, given in Table A2, the expected output of the PV module for the respective 20 states is calculated using Equation (12) and plotted in Figure 4 from 7:00 to 11:00 AM.…”

“…DG allocation and sizing with multi-objective considering real and reactive power losses and deviation in voltage profile have been discussed in [8][9][10][11], only for a constant load and constant generation model. In [12,13], the optimal sizing and placement of DGs have been proposed based on the Hybrid Grey Wolf optimiser (HGWO) and Artificial Bee Colony technique, considering only real power loss reduction, with equality and inequality constraints. In [14], the optimal location and rating of different cases of DG capable of injecting real and reactive power have been proposed based on particle swarm optimisation to minimise real power loss considering the system constraints.…”

This paper investigates the impact of time-varying voltage-dependent load models on hybrid distributed generation planning studies. Firstly, a multi-objective index is constructed with indices namely real and reactive power loss index, voltage deviation index, and mega-volt-ampere capacity index with an objective of reduction of real and reactive power loss, voltage profile improvement, and decreased line loading. The multi-objective index derived is minimised to locate the distributed generation. Secondly, the analytical expression is obtained to size the distributed generation units with the time-varying voltage-dependent load models and probabilistic nature of solar and wind generation. Finally, the impact of load models with the generation effects is separately analysed for PV/wind (hybrid) distributed generation planning. The proposed perspective was validated on the IEEE 33-bus, IEEE 69-bus radial distribution network, and a real 16-bus distribution substation for its effectiveness because the distributed generators are placed in the distribution side of an electrical network. The outcomes reveal that the distributed generation allocation for time-varying voltage-dependent load model and probabilistic nature of solar and wind has significant impacts on the distribution system by reducing real and reactive power loss, improving voltage deviation and reduced mega-volt-ampere intake.

Optimal allocation of shunt capacitors in the radial distribution networks results in both technical and economic benefits. This paper presents a two-stage method of Loss Sensitivity Factor (LSF) and Cuckoo Search Algorithm (CSA) to find the optimal size and location of shunt capacitors with the objective of minimizing cost due to power loss and reactive power compensation of the distribution networks. The first stage utilizes the LSF to predict the potential candidate buses for shunt capacitor placement thereby reducing the search space of the second stage and avoiding unnecessary repetitive load flow while the second stage uses the CSA to find the size and actual placement of the shunt capacitors satisfying the operating constraints. The applicability of the proposed two stage method is tested on the standard IEEE 33-bus and Ayepe 34-bus Nigerian radial distribution networks of the Ibadan Electricity Distribution Company. After running the algorithm, the simulation results gave percentage real and reactive power loss reduction of 34.28% and 28.94% as compared to the base case for the IEEE 33-bus system while the percentage real and reactive power loss reduction of 22.89% and 21.40% was recorded for the Ayepe 34-bus system. Comparison of the obtained results with other techniques in literatures for the standardized IEEE 33-bus reveals the efficiency of the proposed method as it achieved technical benefits of reduced total power loss, improved voltage profile and bus voltage stability, and the economic benefit of reduced total cost due to electrical power loss and compensation.
