In conclusion, energy storage systems play a crucial role in modern power grids, both with and without renewable energy integration, by addressing the intermittent nature of renewable energy sources, improving grid stability, and enabling efficient energy management.
Why is high-voltage transmission important?
High-voltage transmission also enhances voltage regulation, a critical factor in maintaining power quality at the point of consumption. Over long distances, the voltage drop along a conductor can be significant, especially at high current levels. By reducing current, high-voltage systems experience lower voltage drops, ensuring:
How does a power grid work?
The generation side of a power grid mainly operates with high-voltage electricity across a long distance. Generally, the RE systems are utilized as a distributed energy resource (DER) system at the distribution side, whereas the usage of RE systems at the generation side is rarely found with ESS-integrated power grids.
How ESS can help a power grid?
Sometimes, the ESS can support the power grids at the generation side by absorbing the overplus energy to prevent output spikes. ESS can also deliver the stored energy to recover the output drop. This application of ESS can greatly reduce the power quality issue from the distribution side [6, 51].
Why is high voltage electricity important?
Additionally, by transmitting electricity at high voltages with lower currents and minimal losses, utilities can operate more efficiently. This reduces the need to generate excess power to compensate for losses during delivery, leading to lower operating expenses and more sustainable use of energy resources.
