Abstract This paper explores scenarios for powering rural areas in Gaita Selassie with renewable energy plants, aiming to reduce system costs by optimizing component numbers meet demands. Various scenarios, such as combining solar photovoltaic (PV) pumped hydro-energy storage (PHES), utilizing wind PHES, and integrating a hybrid of PV, wind, have been evaluated based on diverse criteria, encompassing financial aspects reliability. To achieve the results, meta-heuristics Multiobjective Gray wolf optimization algorithm (MOGWO) Grasshopper (MOGOA) were applied using MATLAB software. Moreover, optimal sizing has investigated real-time assessment data meteorological from Sillasie, Ethiopia. Metaheuristic techniques employed pinpoint most favorable loss power supply probability (LPSP) least cost (COE) total life cycle (TLCC) system, all while meeting operational requirements various scenarios. The Multi-Objective Grey Wolf Optimization technique outperformed Algorithm problem, suggested results. Furthermore, MOGWO findings, PV-Wind-PHES demonstrated lowest COE (0.126€/kWh) TLCC (€6,897,300), along satisfaction village's demand LPSP value. In PV-Wind-PHSS scenario, are 38%, 18%, 2%, 1.5% lower than those Wind-PHS PV-PHSS at 0%, according Overall, this research contributes valuable insights into design implementation sustainable solutions remote communities, paving way enhanced access environmental sustainability.

Abstract This research discusses the solar and wind sourcesintegration in aremote location using hybrid power optimization approaches a multi energy storage system with batteries supercapacitors. The controllers PV turbine systems are used to efficiently operate maximum point tracking (MPPT) algorithms, optimizing overall performance while minimizing stress on components. More specifically, generator, provided method integrating Perturb & Observe (P&O) Fuzzy Logic Control (FLC) methods. Meanwhile, for turbine, proposed approach combines P&O FLC These MPPT strategies photovoltaic (PV) aim optimize its operation, taking advantage of complementary features two While primary these is both therefore system, they also supply electricity load. For storage, this isolated renewable play crucial role due several specific benefits reasons. Unfortunately, their density still relatively lower compared some other forms storage. Moreover, have limited number charge–discharge cycles before capacity degrades significantly. Supercapacitors (SCs) provide significant advantages certain applications, particularly those that need density, quick charging discharging, long cycle life. However, limitations, such as voltage requirements, make them most effective when combined technologies, batteries.

Analysis and forecasting of electricity prices using an improved time series ensemble approach: an application to the Peruvian electricity market

AIMS Mathematics, Год журнала: 2024, Номер 9(8), С. 21952 - 21971

Опубликована: Янв. 1, 2024

<p>In today's electricity markets, accurate price forecasting provides valuable insights for decision-making among participants, ensuring reliable operation of the power system. However, complex characteristics time series hinder accessibility to forecasting. This study addressed this challenge by introducing a novel approach predicting prices in Peruvian market. involved preprocessing monthly addressing missing values, stabilizing variance, normalizing data, achieving stationarity, and seasonality issues. After this, six standard base models were employed model series, followed applying three ensemble forecast filtered series. Comparisons conducted between predicted observed using mean error accuracy measures, graphical evaluation, an equal statistical test. The results showed that proposed was efficient tool Moreover, outperformed earlier studies. Finally, while numerous global studies have been from various perspectives, no analysis has undertaken learning market.</p>
