Transmission machine energy storage connection path

How can a battery energy storage system improve transmission lines?

To bring more operational flexibility to transmission lines and comply with the electrical sector's digitalization trends, we propose implementing battery energy storage systems at transmission lines with the system's communication protocols and data modelling based on the IEC 61850 standard.

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.

Can energy storage be part of a transmission solution?

For energy storage to be part of the transmission solution, storage developers need to work with transmission owners and follow the Regional Transmission Organization (RTO) transmission planning protocols. Federal Energy Regulatory Commission (FERC) Order 841 mostly treats Electric Storage Resource (ESR) as a generation asset.

Is energy storage a transmission asset?

To date, no FERC order lays out a path for treating energy storage as a transmission asset. One of FERC-jurisdictional RTOs – Midcontinent Independent System Operator (MISO) – has sent a “storage as a transmission-only asset” proposal to FERC, which FERC did not reject but did not approve either.

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.

Are energy storage devices more economical than transmission expansion planning?

The total annual cost of energy storage configuration is about 0.045 billion CNY less than that of transmission expansion planning. Therefore, investing some energy storage devices is more economical when the duration of transmission congestion is relatively short. Table 10.
