This study proposes an optimized model of a micro-energy network (MEN) that includes electricity and natural gas with integrated solar, wind, energy storage systems (ESSs). The proposed is based on hubs (EHs) it aims to minimize operation costs greenhouse emissions. research motivated by the increasing use renewable energies ESSs for secure supply while reducing environment effects. A general a...

In this paper, a valuation method for multi-energy generation plants is presented. The operational flexibility of such plants is modeled using the Energy Hub concept a modeling approach that has been developed in the ”Vision of Future Energy Networks”project at ETH Zurich. The economic value of an Energy Hub including its flexibility is calculated by means of a Monte Carlo simulation method tha...

This paper presents a new method for optimizing the hub height of a wind turbine. In general, wind turbine energy production increases with the hub height, but so does the cost. Therefore, we must optimize the hub height. Here, we calculated the annual energy production using a wind probability function. This is a function of the hub height and the roughness, which is a surface characteristic. ...

Micro-energy grids have shown superiorities over traditional electricity and heating management systems. This paper presents a hybrid optimization strategy for micro-energy grid dispatch with three salient features. First, to enhance the ability support new storage equipment, an energy hub model is proposed using non-supplementary fired compressed air (NSF-CAES). provides flexible cooling, elec...

A p-hub center network design problem is definition of some nodes as hubs and allocation of non-hub nodes to them wherein the maximum travel times between any pair of nodes is minimized. The distinctive feature of this study is proposing a new mathematical formulation for modeling costs in a p-hub center problem. Here, instead of considering costs as a linear function of distance, for the first...

Through a reformulation of energy hubs, this paper presents a novel format for describing general energy hub networks. This format underpins the development of tools for analyzing large-scale interconnected energy hub networks. The tools are developed in MATLAB and seamlessly interface with CPLEX optimization libraries to allow users to quickly implement and solve optimal scheduling problems. O...

within the framework of international political economy, this article discusses the situation of energy resources, including oil and gas, in central asia and argues that due to abundance of oil and gas resources in such countries as kazakhstan, turkmenistan and uzbekistan, and hefty revenues generated by those resources, statesmen in these countries are planning to turn central asia into a majo...
