摘要：The current paper deals with the efficient use of the fossil fuels in the context of DER/DG concept through a unitary approach of the necessary electrical power and thermal energy of an urban peridency and proposes the use of micro-CCHP (trigeneration of electrical power, heat and cold).An analysis of the consumption structures of electrical power and natural gas is provided for the specific conditions of south-eastern regions of Romania. The paper contains a case study which highlights the imbalance between electrical and thermal consumption throughout a year. It also includes a strategy of projecting the micro-CCHP systems according to the ratio between generated electrical and thermal power (P/Pth) by the system and the same ratio for the consumers previously analyzed. The paper presents a proposed structures of micro-CCHP which have as basic thermal engines the fuel celll as well as the overall thermal result of the systems forecast for the critical seasons winter/summer.
