Renewable energy sources and cogeneration costs in aspects of distributed generation

Referat prezentuje zgromadzone doświadczenia i wnioski na temat odnawialnych źródeł energii i generacji rozproszonej funkcjonującej w strukturach scentralizowanego systemu elektroenergetycznego. Wnioski wypracowane z udziałem kogeneracji i źródeł energii różnego pochodzenia uwzględniają konieczność przystosowania systemów generacji rozproszonej do funkcjonowania w elektroenergetycznym systemie scentralizowanym. Referat uwzględnia perspektywy funkcjonowania energetyki prosumenckiej i akcentuje sposób zagospodarowania systemów mikroenergetycznych w scentralizowanym systemie elektroenergetycznym. Skojarzone wytwarzanie energii, przy współudziale źródeł odnawialnych, jest opiniowane w poszczególnych rozdziałach referatu a zauważone problemy i możliwe rozwiązania powstałe w wielowymiarowej energetyce są w publikacji dyskutowane.Author in paper chapters notes that the restructuring of conventional energy power system into a distributed energy system may seek to achieve the effect of increasing number of energy produced from renewable sources and improve efficiency in the power energy infrastructure. The paper presents the collected experience and conclusions on renewable energy and distributed generation functioning in the structures of a centralized energy power system. Can be assumed that some of the aspects of distributed generation noted in the article can be practically used. Reached conclusions include the need to reorganize the conventional energy system with the participation of cogeneration and energy sources of different origin in order to adapt them to the idea of distributed generation. On the basis of the research author notes that distributed energy can be installed in the available infrastructures of power system, and can work in combination due to reduced power transmission losses and achieve greater efficiency in compared to conventional centralized power system. The paper takes into account the perspective of the functioning the prosumer energy system and accentuates the manner of management micro energy systems in conventional power system. The author notes that as a consequence of unplanned aftermath in the energy system components belonging to the structure of the system can be transformed and their effects in stages of restructuring, can be difficult to predict. Combined production of energy with the help of renewable energy is giving opinions in the individual sections of the paper and noticed problems and possible solutions resulting in a multidimensional synergy of energy are discussed in the publication. In this study ways of working and functions of renewable energy in conventional energy systems operating in cogeneration can be interpreted as aspects of distributed energy
