In this paper the authors analyze different alternatives to provide energy utilities to a hospital center with cogeneration systems with diesel engines and gas turbines. The study considers several power sizes and control strategies, so it shows the influence of these parameters, showing that in this case the options with diesel engines are more efficient than the equivalent ones with gas turbi...

A Data Analysis System for Industrial and Enterprise Greenhouse Gas Emission, for meeting the needs of the giant energy-consuming enterprises has been set up through a series of studies on the verification method of Greenhouse Gas (GHG) in industries such as cement, thermal power, cogeneration, transport, sewage treatment etc. The analysis system consists of six modules: Organization Structure;...

The electrical energy is a primary prerequisite for economic growth. Modern power system operates under much stressed conditions because of growth in demand and deregulation of electric power system. Cogeneration and power generation from renewable play a key role in these scenarios. In this paper the affects of DE on the system voltage stability has been assessed. The maximum loadability margi...

In the following a dynamic mathematical model of a generic cogeneration plant with microturbine is described and the corresponding regulating system is realized. The chief aim of this model is the evaluation of the services such a system is able to provide to an interconnected electric network, both in normal operation and in case of wide perturbations, or to an islanded grid in consequence of ...

Hybrid renewable energy systems (HRES) are seeing as a solution to overcome the fluctuation and randomness of certain sources, such solar wind power. Coupling fluctuating sources with controllable biomass-fueled micro-cogeneration, constitute an HRES that significantly reduces CO2 emissions primary consumption. The purpose this work is review research works on hybrid based micro-cogeneration pr...
