Hybrid Technologies for Creating Energy Accumulation Systems

The article discusses the research and development of the electric power storage devices based on hybrid technologies. Studies and analysis of the required conditions for the application of energy storage systems have shown that their main technical characteristics - stored energy, output power and discharge time obviously cannot be implemented in at least scalable but identical technical devices. In order to solve this problem, the hybrid technologies and he differentiation of energy storage systems are used according to the conditions of applying. For example, to ensure the quality of power supply of almost all end-users of the industrial and private sector, it has been proposed to use hybrid accumulation systems based on batteries and supercapacitors. Hybrid power storage systems of this type have identical technical solutions with an operating voltage of 380 volts and a nominal power in the range of units of kilowatts - units of megawatts depending on the power of the storage elements used.

The article shows that ensuring the quality of power supply to consumers of electricity in petrochemical industries subject to emergency shutdowns and significant violations of regulatory requirements for the quality of power supply due to incorrect operation of power supply networks and other high-voltage equipment is possible with the help of hybrid energy storage systems of the kilovolt and megawatt ranges based on batteries of supercapacitors and static compensators of reactive power which allow supporting a required level and quality of the voltage, increase the capacity of transmission lines.
