The There are many factors influencing the performance of photovoltaic (PV) systems. Among these factors, temperature and solar radiation are two major parameters that have a large effect on the efficiency of PV systems. The cell temperature of PV panels is related to the ambient temperature while the solar radiation incident on the surface of the PV modules depends on the slope and azimuth of these modules. Furthermore, ground reflectance (albedo) affects the irradiance incident on the PV panel surface, which in turn affects the output of a PV system. Nevertheless, the effects of these factors on the economic performance of the solar PV systems are scarcely reported. This paper presents a complete design of a stand-alone PV/battery system to supply electric power for a mobile base station in Choman, Erbil, Iraq. The effects of different factors on the total electricity produced by PV arrays and its economic performance are simultaneously investigated. HOMER software has been used as a tool for the techno-economic and environmental analysis. As indicated from the simulation results, the PV array capacity and its economic performance are highly affected by the variation of the slope and azimuth. With a base case (albedo of 20% and average annual ambient temperature of 11°C), the best feasible system which is achieved by facing PV due to south with a tilt angle of 40° or 45°, is found to have net present cost (NPC) of 70595 $ and cost of energy (COE) of 0.54 $/kWh. Moreover, the results indicate that increasing the ground reflectance from 10% to 90% results in a 7.2% decrease in the PV array capacity and about 3% decrease in the NPC and COE. On the other hand, increasing the ambient temperature from 0°C to 40°C results in a 19.7% increase in the PV array capacity and an 8.2% increase in the NPC and COE. Furthermore, according to the ambient temperature of Choman, using PV modules with high sensitivity to temperature is found to be an attractive option. Provided simulation performance analysis proves that the studied parameters must be treated well to establish an enabling environment for solar energy development in Iraq.

A novel control strategy for a hybrid energy storage system in a grid‐independent hybrid renewable energy system

Summary In this paper, a novel control strategy is proposed for a hybrid energy storage system (HESS), as a part of the grid‐independent hybrid renewable energy system (HRES), to maintain active power balance among different constituents of HRES. The considered HRES includes a wind energy conversion system (WECS), a photovoltaic (PV) system, the HESS comprising the battery energy storage system (BESS) and supercapacitor energy storage system (SCESS), dump load, and a set of critical and noncritical loads. The proposed control strategy is executed into two parts: In the first part, the HESS controller maintains the active power balance among different constituents of HRES under variable operating conditions (viz, wind speed, solar irradiance, and load). The low‐frequency components of imbalance power are diverted to BESS for its smooth charging/discharging while the high‐frequency components are diverted to the SCESS, thereby reducing the stress on BESS. Further, the state of charge of the HESS is maintained within the limits and hence increasing its operating life. In the second part, the three‐phase inverter controller, based on vector control technique, regulates the three‐phase AC voltage magnitude and frequency within limits against any perturbation. The novelty of the proposed control strategy lies also in the fact that some portion of the power, which remains uncompensated by BESS when using conventional low pass filter (LPF) scheme, is compensated by SCESS by generating reference current corresponding to this uncompensated power. Further, the synergetic use of the typical HRES—PV system and WECS—and the typical HESS—BESS and SCESS—is also a new proposition. Simulations are carried out in MATLAB/Simulink and the results demonstrate the effectiveness of the control strategy in terms of active power balance of HRES, regulation of DC link voltage (VDC), three‐phase AC voltage and frequency, and maintaining SoC constraints of HESS in transient as well as steady state conditions.

Hybrid renewable energy systems (HRES) are proving a promising solution for rural electrification in India, where grid power availability is limited. This paper aims to identify the optimal design and pre-feasibility techno-economic analysis of the hybrid grid-independent renewable system for rural electrification. The proposed hybrid system integrates the various renewable energy system configurations to provide continuous power for the electric load demands of Kanakadri palle village, Andhra Pradesh, India. HOMER software is utilized to design the proposed hybrid system, perform optimization, techno-economic analysis, and simulation. Here, six different hybrid system configurations were taken into account to perform a comparative economic analysis. The results obtained shows that one of the hybrid systems, PV/DG/converter/battery system (120 kW-PV modules, 54 kW-DG, 200 number of batteries with 260 Ah ratings, and 50 kW-power converters), is the least economical optimal system based on least net present cost and Levelized cost of energy (COE), highest renewable fraction, and zero unmet electric loads percentage (NPC: $341 280, COE: $0.217, highest renewable fraction: 96.6% and unmet electric loads: 0%). For the site considered, this optimal hybrid system can provide a reliable power supply to the total energy requirements of 332.97 kWh/d and achieve 75.68% carbon emission reduction compared to a diesel generator. Moreover, the comparison of different system configurations was carried out based on economic analysis. This analysis shows that proposed hybrid system can be an appropriate model to provide reliable power at a low generation cost for the village considered in this study and can be recommended for future electrification projects.
