Energy storage devices were developed at the Department of Electronics and Electrical Engineering at NSTU. The project was implemented within the frameworks of the grant of Ministry of Education and Science of the Russian Federation.
The energy storage system will not only provide uninterrupted power in case of accidents, but also solve a number of important problems in the energy sector.
«The energy storage devices developed by us will increase the efficiency and stability in electric power supply for consumers, and also will improve the quality of electrical energy. It would allow reducing the wear of electrical networks and electrical equipment. The other problem that will be solved is the provision of additional electricity during peak consumption», the scientific leader of the project, Doctor of Technical Sciences Sergey V. Brovanov says.
The essence of the development is the creation of equipment complex, which allows accumulating electrical energy during the excess period and simultaneously return it to the network during periods of shortage. The system of energy storage during the emergency shutdown of the main power supply will give the possibility to continuously supply electric power to industrial and economic objects, human settlements and other consumers.
Two energy storage devices have been developed at present: ESS-1 (Energy Storage System) with a capacity of 100 to 500 kilowatt-hours and ESS-2 – 2-32 megawatt-hours. A 2-megawatt storage will provide power an average-sized population center for an hour, and the device with 32 megawatt-hour – a small town. The energy storage systems haven’t yet been produced in Russia, they are made only by a few manufactures in the world. It is suggested that the Russian development will be substantially cheaper than foreign analogues. Initially, ESS-1 will cost about 10 million rubles; the price will begin to decline with the output growth.
The first Russian energy storage system of high power will be produced in Novosibirsk and  will be delivered  to the customer by the subsidiary company «DC system» (SPT) in 2018, 80% of which are graduates of NSTU.
NSTU scientists are not going to stop on their achievements but plan to increase capacity of their devices using high-voltage semiconductor converters.
