This paper introduces the concept of a battery energy storage system as an emergency power supply for a separated power network, with the possibility of island operation for a power substation with one-side supply. This system, with an appropriately sized energy storage capacity, allows improvement in the continuity of the power supply and increases the reliability …
Electrical substations are critical components of the electrical grid, ensuring that electricity generated at power plants is efficiently transmitted, distributed, and delivered to consumers. Substations play a vital role in managing the flow of electricity, allowing for reliable and safe power distribution across long distances.
Historically, the role of the substation varies significantly depending on where it is located in the network, however with the changing nature of the grid and more dispersed generation resources, active control will be required at all voltage levels through the network not just at transmission.
The design and integrity of the substation and particularly its ability to recover or endure these disturbances will have a significant impact on the ability to ride through and support restoration of the surrounding networks and eventually the power system.
The adoption of new technology into the substation is a balance of risk and economics. The pace of change is growing and the substation community needs to become faster at successfully implementing change and being responsive to external factors.
This section considers the influence that the change in technologies connecting to the grid and evolving changes system operation behaviour will impose on the functionality of the substation and the equipment there-in. Expect lots of new smaller Distributed Energy Resources (DER) requiring access to substation facilities.
Substation asset management seeks to find the balance and rigour in the trilemma between customers who value reliability and lower costs, stakeholder expectations, and the shareholders and suppliers who seek a reasonable return-on-investment. It is imperative that the utilities consider the total cost of ownership or whole-life value.
