REDUCTION OF MULTI-VERSION ENERGY GENERATION PRIME COST BY USING CURRENTLY MOST PROFITABLE VERSION OF PRODUCTION

摘要

FIELD: electricity.;SUBSTANCE: invention relates to electric engineering and may be used for supplying power to consumers. Prime cost of multi-version energy production is reduced by power supplying facilities and electricity co-generation (conversion of thermal wastes into electric energy and heating) at consumers' point. This method allows for consumer to select one or more types of primary energy from a variety of available energy sources in order to reduce cumulative capital and operational costs and satisfy needs in the own loading. According to the invention, the most profitable current possibilities of energy saving and/or possibilities of money earning by energy exporting to power grid are taken into account. These are the cases when market prices are high and/or it is possible to profit from paying to support grid or provide auxiliary services, is there are any. To support operation requiring high level of reliability, operation without additional costs for redundant lines of power supply connection and expensive backup means of power generation can be ensured at consumer's place.;EFFECT: improved reliability of power grid and consumer power supply systems and wide range of multi-version energy generation application and electric energy co-generation.;15 cl, 7 dwg
