Technical FAQs 4

Can battery energy storage system at a substation improve grid reliability?

Some defense Scheme indicators within Battery Energy Storage System at a substation has been assessed through a software modelling. The results show that Battery Energy Storage System at Substation is able to increase the reliability of grid by such frequency regulation.

Why do substations need a DC power supply?

This output can be utilized while making a battery discharge test during substation commissioning or regular maintenance and testing. Since the DC system supplying specially relay protection, control, and interlocking circuits is of paramount importance to the substation’s reliable and safe operation, the energy supply has to be always available.

Should substations include battery storage?

By incorporating battery storage, substations can ensure a continuous and reliable power supply, even during emergencies. Maintenance programs must be expanded to include electrical substation maintenance routines specific to energy storage interfaces. Visit our Substation Maintenance training course.

How many DC systems can a power substation have?

A power substation can have one or several DC systems. Factors affecting the number of systems are the need for more than one voltage level and the need for duplicating systems. Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.
