This paper discusses the simultaneous management of active and reactive power a flexible renewable energy-based virtual plant placed in smart distribution system, based on economic, operational, voltage security objectives system operator. The formulated problem aims to specify minimum weighted sum energy cost, loss, index, considering optimal flow model, formulation, operating model plant. unit includes sources, like wind systems, photovoltaic, bio-waste units. Flexibility resources include electric vehicle parking lot price-based demand response. In mentioned scheme, parameters load, vehicles, prices are uncertain. utilizes Unscented Transformation method for modeling uncertainties. Fuzzy decision-making is utilized extract compromised solution. suggested approach innovatively considers with vehicles performed promote network objectives. According numerical results, units capable boosting operation, status by approximately 43%, 47-62%, 26.9%, respectively, studies. Only response can improve security, economic states about 19.5%, 35-47%, 44%, compared model.

The status and potential of regional integrated energy systems in sub-Saharan Africa: An Investigation of the feasibility and implications for sustainable energy development

Energy Strategy Reviews, Journal Year: 2024, Volume and Issue: 53, P. 101402 - 101402

Sub-Saharan Africa (SSA) is experiencing rapid economic growth and rising demand for energy, accompanied by significant low energy access sustainability challenges. Globally, to address similar issues unlock a region's potential, regional integrated systems have gained traction, initiatives such as establishing power pools electricity markets, cross-border exchanges, integrating renewable resources are being promoted. This paper describes the status of in Africa. We analyze achieved through effective strategies policies that support developed developing regions (the United Kingdom China). Our findings show challenges, including limited financing, regulatory barriers, lack planning model, inadequate supporting policies, fragmented institutional frameworks, hinder widespread deployment systems. Taking lessons from case studies, addressing SSA's challenges requires concerted efforts governments, international organizations, private sector create enabling policy environments, mobilize investments, build technical capacity infrastructures. Regional can enhance security diversifying sources, fostering development, stimulating trade. In Kingdom, implementation has contributed 25% reduction carbon emissions 15% increase efficiency over past decade. Similarly, China, integration sources into led 30% 20% decrease coal consumption since 2010. China owns 32% global market, alongside an installed about 1.26 TW first quarter 2023. indicate three out four possess hydro resources. Specifically, within CAPP region, 7 10 countries heavily rely on while EAPP, 6 11 exhibit dependency. Moreover, SAPP, 9 12 WAPP, 5 14 significantly energy.
