A direct expansion (DX) HVAC system is an efficient way to supply fresh and dehumidified air to a built environment. To improve the efficiency of a conventional DX system in hot and humid regions, fresh air dehumidification and conditioning systems with energy recovery measures are the key equipment to reach such a goal. To achieve this goal an integrated system is proposed. The integrated syst...

This paper presents a formulation of unit commitment for thermal units integrated with wind and solar energy systems and electrical vehicles with emphasizing on Mixed Integer Nonlinear Programming (MINLP). The renewable energy resources are included in this model due to their low electricity cost and positive effect on environment. As well as, coordinated charging strategy of electrical vehicle...

A systematic method has been developed to study the integration of polygeneration systems in industrial processes and/or urban systems. Several aspects are analyzed with a holistic vision. For given system’s boundaries, the energy services and energy requirements are first characterized. This requires the analysis of the different services and production operations needed. In an industrial proc...

This study evaluated the energy saving potential of renewable generation systems based on integrated solar in an urban environment. The city concept was implemented using photovoltaic (PV) and thermal systems. As a case study, Sejong national pilot smart South Korea selected to evaluate penetration rate. For evaluating proposed systems, electrical loads were estimated field measurement data. Th...

The community integrated energy system (CIES) is an essential internet carrier that has recently been the focus of much attention. A scheduling model based on chance-constrained programming proposed for demand response (IDR)-enabled CIES in uncertain environments to minimize operating costs, where IDR program used explore potential interaction ability electricity-gas-heat flexible loads and ele...

The integrated energy system is an effective way to achieve carbon neutrality. To further exploit the reduction potentials of IESs, optimal dispatch strategy that considers demand response and stepped trading proposed. First, (IDR) pricing approach proposed based on characteristics different load types. Classify multi-energy loads into curtailable substitutable loads, incentivize both through a...
