Energy storage to prevent reverse power transmission

How can energy storage reduce the investment in power transmission & distribution equipment?

Therefore, energy storage can store the energy during the peak periods of the renewable energy outputs and release it during the uncongested periods, which can also reduce the investment for power transmission and distribution equipment. Fig. 11. Power flows of B5–10 under several typical scenarios. 5.2. Case 2: a practical 129-bus system 5.2.1.

Can energy storage improve the flexibility of power system operation?

Numerical experiments are carried out on a modified IEEE-RTS 24-bus system and a practical 129-bus system. Numerical results show that energy storage can improve the flexibility of power system operation and the utilization of renewable energy generation.

Can energy storage reduce transmission congestion?

Basic data and calculation assumptions From Case 1, it can be seen that energy storage is helpful for alleviating transmission congestion. And in Case 2, an economic analysis is conducted on a practical 129-bus system, which can check the feasibility and economy of the proposed method.

Should a generator be a reverse energy protection device?

As a result, the generator will become a synchronous motor and will actually cause significant mechanical damage. The reverse energy protection device should be included in the generator protection scheme. Smart grids use communication networks with sophisticated algorithms to ensure coordination between protection systems.

What happens if reverse power is not considered in a protection system?

Otherwise, when failure or improper operation occurs, the reverse power condition may occur. If the reverse current is not considered in the design of the protection system, this will create massive problems. The purpose of this study was to investigate the reverse power of generation units.

What are the advantages of optimal configuration method of energy storage?

3. The proposed optimal configuration method of energy storage can improve the operation flexibility of power system and the utilization of renewable energy generation. Therefore, it overcomes the disadvantages of traditional transmission network expansion planning, such as high investment cost and poor economic performance.
