We propose stochastic control policies to cope with uncertain and variable gas extractions in natural networks. Given historical extraction data, these are optimized produce the real-time inputs for nodal injections pressure regulation rates by compressors valves. describe random network state as a function of inputs, which enables chance-constrained optimization arbitrary topologies. This ensu...

The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...

The greatest contribution to greenhouse gas emissions is the burning of fossil fuels, which releases nearly six billion tons of carbon per year into the atmosphere. These fuels will continue to be used well into the 21st century, although there is a urgent need to manage a sustainable economic development. Since power plants are the largest point sources of CO 2 emissions, capturing the carbon ...

This article focuses on issues related to control and operability of a Solid Oxide Fuel Cell (SOFC) Gas Turbine (GT) hybrid system with single-shaft GT configuration. The models of all the components of the hybrid system are developed and integrated to constitute the hybrid system. An autonomous power grid is modeled as load. The main control objectives considered are control of Fuel Utilizatio...

geothermal energy because of its versatility has extensive applications in power generation, industry, agriculture, treatment of diseases etc: ...this source of energy has received great attention in recent years many countries in the world are benefiting from it. it possesses an eternal heat source and is pollution free. in this article it is tried to demonstrate the importance of georhermal e...

This paper presents an approach for the combined optimization of energy systems including multiple energy carriers such as electricity, natural gas, and district heat. Power flow and conversion between the different energy infrastructures are described as multi-input multi-output coupling, what enables simple analysis and optimization of the flows. While previous work deals with operational opt...
