The basic form of the Power Station can only draw a certain amount of power from the main grid. The capacity currently used is shown by a bar to the left of the tile. When this limit is reached, the bar will flash and when filled the Power Station will stop functioning. The capacity, however, can be increased.

A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel to store electrical energy in an electric power system.Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulating material. Capacitor banks are used for various purposes, such as

Capacitors in Solar Systems: Solar PV Inverters. Capacitors play a critical role in the solar market. Among other uses, they are employed in PV inverters, which are devices that convert the DC power produced by solar
The new power station further grew in installed capacity to 13.75 MW. Despite this growth, between 1944 and 1948, Nigeria started experiencing a decline in the use of coal for electricity generation as a result of reduced mining activities, as well as the small discoveries of crude oil to the large scale discovery of oil in Nigeria in 1956. Due to frequent outrages, the Niger Dams
Substation transforms voltage from high to low or from low to high as necessary. Substation also dispatches electric power from generating stations to the consumption center. Electric power may flow through several substations between the generating plant and the consumer, and the voltage may be changed in several steps. Contents:

Capacitor Bank. A capacitor bank is a group of capacitors connected in series or parallel combinations. Capacitor banks store reactive energy, which can compensate for reactive energy and improve the power factor. This leads to a more stable grid with higher transmission capacity and fewer transmission losses.
Capacitor banks are critical components in substations, playing a pivotal role in maintaining power quality and stability within electrical distribution systems. These devices consist of multiple capacitors connected either in series or parallel, functioning as a unified system to store and release electrical energy as required.

1. Static Capacitor. We know that most industries and power system loads are inductive, which causes a decrease in the system power factor due to lagging current (see disadvantages of low power factor).To improve the power factor, static capacitors are connected in parallel with these devices operated on low power factor. These static capacitors supply leading current, which

Distribution capacitors areinstalled close to the load, on the poles, or at the substations. Although these capacitor units provide reactive power support to local load, they may not help reduce the feeder and transformer losses. Low voltage capacitor units are cheaper than high voltage capacitor banks.
The capacitor bank is installed close to the loadto provide reactive power locally. In a system in which a large number of small equipment are compensated, the reactive power demand may fluctuate, depending on the load. During off-peak load condition, the capacitor bank voltage may go up and hence overcompensation should be avoided.
