Integrating renewable energy (RE) into electricity generation enhances sustainability, reduces greenhouse gas emissions, improves security, lowers costs, and supports sustainable development, particularly in remote underserved regions. This study evaluates the feasibility performance of a hybrid system (HRES) designed to meet demands Hobyo Seaport, Somalia. The proposed HRES incorporates photovoltaic (PV), wind turbines (WT), diesel generator (DG), pumped hydro storage (PHES), battery (BESS). Four configurations-PV/WT/PHES, PV/WT/DG/PHES, PV/WT/DG/BESS, WT/DG/PHES-were analyzed using HOMER Pro MATLAB software optimize sizing assess techno-economic environmental performance. Results indicate that PV/WT/PHES configuration is most efficient, achieving 100% fraction, net present cost $619,720, lowest levelized at $0.03845/kWh, simple payback period 0.31 years. Additionally, offers significant benefits, mitigating 1,029 tons CO annually, valued $20,593 carbon credits. Over 20-year period, it cumulative cash flow by 97.1% compared diesel-based system. These findings highlight as cost-effective environmentally advantageous solution, establishing its sustainability practicality for enhancing infrastructure Somalia's Seaports similar coastal

Microgrids are considered a practical solution to revolutionize power systems due their ability island and sustain the penetration of renewables. Most existing studies have focused on optimal management microgrids with fixed configuration. This restricts application developed algorithms other configurations without major modifications. The objective this study is design rule-based modular energy system (EMS) for that can dynamically adapt microgrid To realize framework, first, each component modeled as separate entity its constraints bounds variables. A wide range components such battery storage (BESSs), electric vehicles (EVs), solar photovoltaic (PV), microturbines (MTs), different priority loads modules. Then, designed analyze impact presence/absence one module others update constraints. For example, load shedding PV curtailment be permitted if grid not included. present in any given configuration communicated EMS, it optimizes operation available components. could simple flexible operating grid-connected mode or complex hybrid AC DC buses diverse equipment side. facilitate realization configurations, AC/DC where utility interlinking converter (ILC) also proposed method used test performance both islanded modes by simulating four typical case. Simulation results shown optimize configurations.
