The aim of this work is to develop approaches for a methodology creation that allows estimate preliminary assessment of the power consumption management potential in the absence of experimental data on the object under actual load study. Analysis of diesel power plants operating modes in such systems showed that diesel generators often operate in suboptimal load ranges, which leads to increased diesel fuel consumption, reduction in diesel generators service life andas a result of poor diesel fuelcombustion in the cylinders or increased mechanical parts wear, etc. At the same time, electricity

Abstract:

The normalized accuracy of the installed measuring instruments determines the scheduled measurement accuracy of the daily active load of an industrial enterprise. To maintain it during operation, syntactic and semantic methods can be used to control the reliability of load measurements. During syntactic control, the state of measuring instruments that collect and process information about the enterprise’s load is diagnosed. Semantic control is based on the use of probabilistic characteristics of the measured load. The condition necessary for semantic control is the presence of information redu

Abstract:

With the emergence of the smart grid, both consumers and electricity providing companies can benefit from real-time interaction and pricing methods. In this work, a smart power system is considered, where consumers share a common energy source. Each consumer is equipped with a home energy management controller (HEMC) as scheduler and a smart meter. The HEMC keeps updating the utility with the load profile of the home. The smart meter is connected to a power grid having an advanced metering infrastructure which is responsible for two-way communication. Genetic teaching-learning based optimizati

The use of large amounts of existing baseload NPPs capacities with a significant increase in renewable generation in the mathematical model of optimal dispatching of generating capacities of Ukraine’s power system leads to a significant surplus of electricity during peak power generation at solar PV’s, which necessitates additional sources of flexibility of the power system, such as battery electricity storage systems.

It determines the full potential of maneuvering power of electric heat generators to provide ancillary services to a power system. Moreover, due to the decline of the Ukrainian population and the decrease of demand for thermal energy, it is expected to decline in the future and will reach 1.9 GW in 2050 (down 36.6% compared to 2020).

Abstract New trends in the fight against climate change on the planet, suggesting a reduction in greenhouse gas emissions, are influencing the formation of a new structure of the electric power system. As the experience of the European Union shows, the active development of renewable energy sources affects the electrical modes of operation of power plants and in the future can lead to a decrease in electricity production in a highly efficient combined generation mode at CHPPs. Thus, there is an acute issue of finding a place for a CHP plant in the emerging power systems, in which generating eq
