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.
