Volt-VAR optimization (VVO) has been investigated extensively in power systems. However, under the era of integrated energy systems (IES), growing interdependencies between different complicate traditional VVO. This is further hardened by incurred gas quality problems due to hydrogen injection IES, produced widely applied power-to-gas (P2G) facilitates that couple and paper develops a two-stage...

Because of the growing concerns regarding climate change and energy sustainability, a transition toward modern sector that reduces environmental effects while promoting social economic growth has gained traction in recent years. Sustainable solutions, which include renewable low-carbon sources such as nuclear natural gas, could minimize emissions greenhouse gases, enhance air water quality, enc...

In this letter, we propose a market-based bi-level conic optimal energy flow (OEF) model of integrated electricity and natural gas systems (IENGSs). Conic alternating current power (ACOPF) is formulated in the upper-level model, generation cost fired units (NGFGUs) calculated based on locational marginal prices (NG-LMPs). The market clearing process system modeled lower-level model. bilevel the...

climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...
