Andrusenko S.I., Bugaichuk O.S., Budnychenko V.B., Podpisnov V.S. Business case for application of energy storage units in urban transport and home power grids. Visnyk National Transport University. Series «Technical sciences». Scientific and Technical Collection. - Kyiv: National Transport University, 2020. - Issue 1 (46).

The article deals with the methodology of business case for application of energy storage units in urban transport and home power grids while using dual- and three-zone pricing; in addition it provides an example of the methodology application.

The object of study are electrical grids with energy storage units.

The purpose of the work is to develop the business case for application of energy storage units in urban transport and home power grids while using dual- and three-zone pricing.

Methods of investigations - mathematical modeling of processes.

As a rule, the volumes of electricity production and its consumption do not coincide in time. Therefore, energy storage units are used to optimize energy flows. The drive is charged with an excess of energy and transfers the stored energy to the system at the moments of its absence. The development of such technologies can have a significant economic effect and is of great practical importance. In Ukraine, dual­zone and three-zone pricing are set for the population and businesses. When using the dual-zone pricing, the energy price coefficients for households are 0.5 at night from 11 p.m. to 7 a.m. and 1.0 in the daytime. The maximum operation of urban electric transport, as well as power consumption by enterprises, organizations and households, occurs at the time of day with the highest energy price. To reduce overall consumption, you can charge energy storage units at night and use the stored energy during the day.

The methodology for business case for application of energy storage units by using dual-zone and three-zone pricing is proposed. We have obtained the criteria for this need. To calculate the payback period of the project, we use the method of expected current clean price is used. It is shown that at the existing prices of energy storage systems and electricity pricing in Ukraine, the use of such systems to save money due to low night pricing is impractical. It was determined that business case for application of energy storage units when using a dual-zone pricing in Ukraine can take place if only specific electricity pricing from available units is less than 0.2 ... 0.7 UAH/kWh.

The results of the study can be used in the design of electrical systems with energy storage units.

The predicted assumption about the development of the object of study is to determine business case for application of energy storage units in consumer power circuits using alternative sources of electricity.

KEYWORDS: ELECTRICITY, STORAGE UNITS, PRICING, ELECTRIC TRANSPORT, HOUSING, INVESTMENT, ECONOMIC EFFECT, EXPECTED CURRENT CLEAN PRICE, PAYBACK PERIOD.
