“…Hybrid system for Biret using HOMER simulation . Source: Simulation by HOMER factor in this digital implantation is related to the estimated lifetime of the project, which is generally estimated for 25 years (Adaramola et al, 2014). The calculations presented by the software take into account values such as interest capital, depreciation, operating costs, fuel costs.…”

The purpose of this work is to study the optimization of an hybrid system of electricity production (solar-diesel with storage) of Biret (Mauritania) using the Hybrid Optimization Model for Electric Renewables (HOMER) software. Indeed, it shows that the context and behavior of the chosen system is optimal. HOMER is used to present simulations in the most economical way. It is important to note that the application of HOMER (using meteorological data obtained on the site) analyses the profitability or otherwise of the technologies used in Biret and proposes a hybrid system, taking into account the economic aspects of the project. From this perspective, simulations can be carried out to obtain the best configuration of the hybrid system used for electricity production in Biret. These simulations show the economic optimization of an electricity production using a hybrid system. To this end, a pilot installation, based on this concept, was carried out in Biret. It consists of a 61.44 kw solar field and a 40 kW generating set with 2950 Ah storage system. Optimization of the pilot unit was first studied using the solar-diesel system and secondly by operating the diesel coupled to the storage system. This led to the conclusion that a slight increase in sunshine will result in a decrease in the price of Kwh. On the other hand, that any increase in the price of diesel, while maintaining the constant sunshine will lead to an increase in the price of Kwh. This makes it possible to position this paper in terms of optimal management of the hybrid electricity production system, as a first step of popularizing the photovoltaic systems in the countries of Sahel.

“…The OPEX on sites powered by DG alone is higher than that in hybrid powered sites. Carbon footprint savings of 30~75% are also achieved as a result of the reduction in the burning of fossil fuel [29][30][31][32][33][34][35]. (2) A 50% reduction in OPEX of traditional energy source (DG) and above [33,36].…”

Abstract:As more locations gain access to telecommunication, there is a growing demand to provide energy in a reliable, efficient and environmentally friendly manner while effectively addressing growing energy needs. Erratic power supply and rising operation costs (OPEX) in Nigeria have increased the need to harness local renewable energy sources. Thus, identifying the right generator schedule with the renewable system to reduce OPEX is a priority for operators and vendors. This study evaluates the energy costs of hybrid systems with different generator schedules in powering base transceiver stations in Nigeria using the Hybrid Optimization Model for Electric Renewable (HOMER). A load range of 4 kW to 8 kW was considered using: (i) an optimised generator schedule; (ii) forced-on generator schedule and (iii) the generator-only schedule. The results showed an optimal LCOE range between averages of USD 0.156/kWh to 0.172/kWh for the 8 kW load. The percent energy contribution by generator ranges from 52.80% to 60.90%, and by the solar PV system, 39.10% to 47.20%. Excess energy ranges from 0.03% to 14.98%. The optimised generator schedule has the highest solar PV penetration of 56.8%. The OPEX savings on fuel ranges from 41.68% to 47% for the different load schedules and carbon emission savings of 4222 kg to 31,428.36 kg. The simulation results shows that powering base stations using the optimised hybrid system schedule would be a better option for the telecom industry.

“…This provides a gap in knowledge about costing variables necessary for the analysis of projects. Adaramola et al, 2014 authored a highly cited assessment of off-grid PV solar-diesel power systems for use in Nigeria that assumed capital costs of different technologies would be similar to those advertised on local market watch website (Muyiwa S. Adaramola, 2014). Similar websites exist in Australia due to the competition in the industry of PV panels, inverters and batteries; making up-to-date market prices easily accessible.…”

“…Adaramola et al, 2014 assume a 10% hourly spinning reserve is sufficient for their system as well as 25% of the current renewable energy output (Muyiwa S. Adaramola, 2014). This assumption is also used for the Lord Howe Island project and various HOMER simulations in international countries (David Pollington, 2015, p. 84) (Lanre Olatomiwa, 2015, p. 442).…”

They estimated that the price would be double that reported on wholesale solar after import duties and currency exchanges was completed.…”

Hybrid systems are gaining momentum for remote areas as they can lower the cost of electricity by integrating with existing diesel/liquid fuel generation. This report will outline the assumptions used to compare multiple remote Australian electricity generators in order to make it easy to replicate similar models for the future. Comparing various different locations will help to predict how the uptake of hybrid diesel/solar/battery systems could change in the future. This is significant, as it will clarify some of the constraints that are holding back smaller diesel generators from integrating renewable technologies. Simulating multi-year, hour-by-hour weather and energy demand data through a hybrid modelling software called HOMER, will indicate the lowest cost energy mix under different scenarios. It will give an indication of whether some off-grid communities are more desirable investment opportunities than others, but is not a concrete prediction. The assumptions made in this report were sometimes necessary in the absence of real life data. Accurate energy consumption data could reduce some bias and improve the accuracy of the predictions.
