Optimal operation of energy hub based microenergy network with integration of renewables and energy storages

This paper proposes the optimized model of Microenergy network (MEN), which includes electricity, natural gas with the integration of solar, wind and energy storage systems, based on the energy hub (EH) model, to minimize operational costs and greenhouse emissions (NO₂, SO₂, and CO₂ ). The research was motivated by the increasing use of renewables and energy storage for secure energy supply while lower operational costs and environment influence. General Algebraic Modeling System (GAMS) is used to solve the optimal operation problem within MEN. The results demonstrate that an optimal MEN formed by multiple EHs can provide appropriate and flexible responses to changes in electricity price and adjustments between time periods and seasons, along with significant reduction in operational costs and emission. The proposed MEN model contributes to future research by suggesting a more efficient network model approach (compared to traditional electricity supply system) to scale down the environmental and economic impacts of electricity storage and supply system in operation.
