Matching energy prices in power generation systems

The article refers to the impact of energy prices on the economical range of fossil fuel engine power regulation. Article
is making reference also to the use of renewable energy sources as a complement to the power generator consuming
fossil fuel and to the use of renewable energy sources in the national power system. The characteristics obtained in the
article are based on a simplified model of a classical thermodynamic engine operating in combined heat and power
generation cycle. Energy costs and prices which include energy losses and energy costs without energy losses in the
engine are here compared. The publication also include the role of cogeneration in distributed power generation and
consider different possibilities of using combined heat and power cycle. Article gives a way to calculate the costs of
energy production, which allowance the energy losses resulting from heat efficiency of fossil fuel engine. In summary
article is making reference to the use of renewable energy sources as a complement to the energy production fossil fuels
engines.
