Methodology for determining technical, economic and environmental performance of combined power plants

Consideration of the feasibility building combined power plants (CPP) based on renewable energy sources (RES) and choice parameters, type equipment, layout, design solutions is an assessment economic efficiency, indicator which ratio between required investments achieved technical effect. An accurate efficiency a rather difficult task since it necessary to take into account large number factors, for example, specific features solutions, operating conditions CPP depending requirements consumer, stochastic nature manifestation resources, possible mode operation needs individual consumers others. approach minimum cost criteria has been widely used justification objects under construction long time. In rigidly centralized management, such ensuring optimal planning played important role in increasing scientific validity decisions. It proceeded from global national goals development. free market economy, method evaluating effectiveness taking all main necessary.
