“…The installation of a tank of network hot water improves the economical effectivity of cogeneration, and thus also to a further increase of the optimal value of the share of cogeneration. The results presented in this paper indicate that the optimal share of cogeneration in district heating systems grows additionally by about 10% in comparison with the results attained by the authors of [13].…”

“…The objective function in the optimization supplemented by additional components concerning thermal storage takes, in comparison with [13], the following form: Red certificates are assigned when electricity is produced in the highefficiency cogeneration. The criterion of the qualification of high-efficiency cogeneration depends on the value of the PES (primary energy savings) index [2,7,10]:…”

The paper presents the results of optimizing the coefficient of the share of cogeneration expressed by an empirical formula dedicated to designers, which will allow to determine the optimal value of the share of cogeneration in contemporary cogeneration systems with the thermal storages feeding the district heating systems. This formula bases on the algorithm of the choice of the optimal coefficient of the share of cogeneration in district heating systems with the thermal storage, taking into account additional benefits concerning the promotion of high-efficiency cogeneration and the decrease of the cost of CO2 emission thanks to cogeneration. The approach presented in this paper may be applicable both in combined heat and power (CHP) plants with back-pressure turbines and extraction-condensing turbines.

The goal of the paper is to presents the results of the energy, economic and environmental assessment of biomassfired combined heat and power (BCHP) units cooperating with the district heating system. The mathematical models of both considered BCHP units (with back-pressure and extraction-condensing turbines) have been elaborated and validated with the data from commercially available CHP units.The results of this study prove that BCHP units can be a good option for the Polish energy sector, both from an environmental and energy point of view. The economic analysis showed that the analysed BCHP units could be profitable, but the are several factors, like prices of guarantees of origin for electricity producted from renewable energy sources, that strongly affect the results.
