Summary: This paper presents the optimal integration of wind turbines and/ or photovoltaics with membrane-based seawater desalination units to fulfill freshwater demand. The possibility of variable freshwater storage is considered for a cost-effective process design. Total cost minimization is the objective function. Real data on renewable resources from NASA is used. No electrical grid connection is taken into account. The implemented model evaluates the capacity of wind and solar energy in meeting variable freshwater demands based on meteorological data. Two cities in Argentina, Rio Grande and Camarones, are used as case studies to compare optimal solutions obtained using solar and/or wind systems.

Summary: This study analyzes the solar-wind hybrid renewable energy systems in 36 typical locations in China, examining the effects of wind and solar energy resources on system reliability and optimal capacities. The results show that in certain locations, the system's levelized cost of energy can be significantly reduced by effectively utilizing wind and solar energy, with the complementary characteristics of these two forms of energy playing an auxiliary role in improving reliability and reducing costs. Wind farms and PV plants still hold the greatest cost advantage in locations with different resources, but the integration of an electric heater with thermal energy storage and a power cycle can greatly enhance reliability and economy. The introduction of concentrated solar power plants is recommended in most regions where high reliability is pursued, and the commercial promotion of CSP plants brings the most significant economic benefits.

Summary: Recent advances in electric grid technology have enabled the development of sustainable, modern, decentralized, bidirectional microgrids (MGs) that can support renewable energy sources, energy storage, power converters, and energy management systems. This paper proposes a hybrid MG system that utilizes solar photovoltaic, wind turbines, biomass gasifiers, batteries, and a backup diesel generator to meet the energy demand of Basra, Iraq. The system's optimal sizing is determined using the Hybrid Grey Wolf with Cuckoo Search Optimization (GWCSO) algorithm, which outperforms other optimization algorithms in terms of cost and performance. The simulation results show that the proposed system has a Levelized Cost of Energy (LCOE) of 0.1192 and an overall cost of approximately USD 2.6918 billion.

Summary: This paper explores the integration of renewable energy sources into transportation networks. Through the comparison of different sizing and placement scenarios, it is found that low-traffic substations are best suited for PV systems with daily storage, high-traffic substations should be without storage and sized below their energy neutrality point, and a hybrid solution of 53% PV and 47% Wind offers the best outcome. The centralized energy-neutral approach with Wind and PV can provide a direct bus load coverage of 54.1%.

Summary: The study proposes a deterministic algorithm and utilizes genetic and artificial bee colony (ABC) optimization algorithms for optimal sizing of PV/battery and PV/WT/battery hybrid systems in Nigde and Bozcaada, Turkey. Experimental results show that optimal sizing is different for each location due to different wind and solar characteristics. The ABC algorithm demonstrates better performance and less execution time for optimizing hybrid renewable energy systems.
