Busan South Korea Peak Loading and Frequency Regulation Energy Storage Power Station

What is frequency regulation in Korea?

In Korea, frequency regulation is governors are to respond within 10 seconds and provide power for 30 seconds; and through automatic generation control (AGC), wherein a power plant must respond within 30 seconds and provide power for 30 minutes.

What is the maximum output power of energy storage peak regulation?

The energy storage output and SOC changes are shown in Figure 5 and Figure 6. The maximum output power of energy storage peak regulation is P1max = 0.13 MW.

Are fast-responding frequency regulation systems a threat to power systems?

Fast-responding frequency regulation systems are gaining greater importance in power systems of the future due to the increasing integration of renewable sources in power grids across the globe. This increase poses a threat in maintaining an inherent property of traditional power grids; it is often referred to as system inertia.

Can small capacity energy storage power stations compete for frequency regulation services?

At present, China’s small capacity energy storage power stations cannot be allowed to compete for frequency regulation services, but the establishment of auxiliary service markets such as frequency regulation and standby is conducive to guiding investment to improve the flexibility of power systems [19, 20, 21, 22, 23, 24, 25].
