“…Weather and geographic characteristics of the decentralized zones in question make it practically possible to use only wind and solar energy out of all types of renewable energy sources. Since electric power consumers need an uninterruptible power supply, hybrid power plants on the basis of diesel generator sets [1][2][3] are the most promising way to build autonomous power supply systems. One of the technical solutions to increasing the efficiency of autonomous power supply systems is changing the DGS operating mode from constant speed to variable speed, optimized according to the size of the electric load [4].…”

“…The positive effect of the heat pumps implementation in CHP operation depends on its working mode. When operating in the condensing mode AHP can be used for fuel-flow condensate heating, and in heat-extraction mode it can be used for heating the main condensate, delivery water, raw water used for the station needs [4,5] after chemical cleaning (including heat supply makeup).…”

The article deals with a comparative analysis of CHP operational efficiency in various working modes before and after the absorption heat pumps installation. The calculation was performed using a mathematical model of the extraction turbine PT-80/100-130/13. Absorption heat pumps of LLC "OKB Teplosibmash" were used as AHP models for the analysis. The most effective way of absorption lithiumbromide heat pumps application as a part of the turbine PT-80/100-130/13 turned out to be their usage in a heat-producing mode during a non-heating season with a load of hot water supply. For this mode the dependence of the turbine heat efficiency on the heat load of the external consumer at a given throttle flow was analyzed.

At present, the influence of technologies on the environment became comparable with natural processes at the Earth. Therefore, the use of renewable energy sources, including water resources, is very important for the energy market operated as the Internet of things. The present paper proposes a universal method for analyzing the efficiency of technical systems using the combination of an optimization method and a method of marginal utility evaluation. Based on the comparison of water volume at a hydropower plant (HPP) and fuel amount at a combined heat and power plant (CHPP) that is used for generation of 1 kW power, it is possible to determine a water price for a HPP. Using the examples of Novosibirsk HPP and CHPP, it is expected to develop an estimation of economic effect from the implementation of the developed criteria, the proposed method of determination of a water price at HPP, and the method of separating fuel costs at CHPP. As a result of implementing the developed method for theHPP, theprice of sold electricity in the flexible energy market will be comparable with the price for sold electricity produced at theCHPP, being equal to approximately 330 RUB/MW·h. Moreover, CHPP are expected to have savings of specific fuel consumption for electricity generation in the amount of 5 g/kW·h and, in some case, 10 g/kW·h. In terms of money, this amounts about 7,350,000 – 14,700,000 RUB per month.
