What is a battery storage power station? A battery storage power station, also known as an energy storage power station, is a facility that stores electrical energy in batteries for later use.
The term battery system replaces the term battery to allow for the fact that the battery system could include the energy storage plus other associated components. For example, some

A substation grounding system has two main parts: the grounding network and the connection to the earth. The grounding network bonds all equipment frames and metallic structures in the substation, while the connection to the earth is the interface between the electrical system and the earth.
The grounding grid should cover as much ground as possible in the substation, including an area outside the fence. The conductors will be laid in parallel, trying to maintain a uniform spacing along the rows of equipment and structures in the substation. This arrangement will simplify the connections.
There are three main methods to connect a substation grounding network to the earth: The radial system consists of one or more grounding electrodes with connections to each device in the substation. It is the most economical, but the least satisfactory because, when a ground fault occurs, it produces enormous surface potential gradients.
Substation safety requires the grounding and bonding of all exposed metal parts. The metallic structures, generators, transformer tanks, circuit breakers, switchboards, switches, metal walkways, steelwork of buildings, fences, instrument transformer secondaries, capacitors, lightning arresters, surge arresters, and reactors must be grounded.
Where an industrial or commercial power system includes power-generating equipment, the reasons for grounding these components may be the same as those for grounding similar components of public utility systems. The methods of grounding would generally be similar under like conditions of service.
Grounding of an electrical system is a decision that must be faced by engineers charged with planning or modifying electrical distribution. Grounding in some form is generally recommended, although there are certain exceptions. Several methods and criteria exist for system grounding; each has its own purpose.
