Why do substations need advanced control systems and energy storage technologies?

Substations equipped with advanced control systems and energy storage technologies can store excess renewable energy during periods of high generation and release it when generation is low. This capability is crucial in ensuring that renewable energy can be reliably integrated into the grid.

What does a substation do?

U.S. Electric System Overview Substations serve as critical nodes connecting generation, transmission, and distribution networks. While substations are used for several distinct system functions, most utilize electric power transformers to adjust voltage to match varied voltage requirements along the supply chain.

What are the components of a substation?

The primary components of a substation include: Transformers: These devices change the voltage levels of electricity to make it suitable for either long-distance transmission (high voltage) or local distribution (low voltage). They consist of a core and windings that convert electrical energy through electromagnetic induction.

What is a transmission substation?

Transmission substations handle high-voltage electricity and serve as interconnection points between different transmission lines. Distribution substations reduce voltage levels for local distribution, while generation substations connect power plants to the grid.

What equipment is used in a substation?

Circuit breakers: They protect the substation from faults by interrupting the flow of electricity if something goes wrong. ● Switchgear: This equipment is used to isolate faulty parts of the substation or electrical grid during maintenance. ● Busbars: These conduct electricity throughout the substation, distributing power where needed.

How are substations being upgraded?

Substations are being upgraded to include intelligent electronic devices (IEDs), advanced sensors, and automated controls that enable real-time monitoring and response to changes in the grid.
