Why is PSO a good choice for a multi machine power system?

Multi machine power systems are highly dynamic, with changing load conditions and the integration of renewables affecting frequency stability. PSO's inherent adaptability to dynamic changes in the optimization landscape makes it well-suited for handling such complexities in frequency regulation tasks.

Is energy storage frequency regulation loss based on SoC?

Existing research on energy storage frequency regulation loss mainly focuses on two aspects : one is to establish a loss model based on SOC, and the other is to establish a loss cost model. According to the real-time AGC instruction. Literature [17, 18] has proposed supplementary control units for battery energy SOC management.

How to ensure the stability of a power system?

To ensure the stability of the power system, the output power of each power source (considering capacity factor), the transmission power of the transmission line, and the charging and discharging power of the energy storage must satisfy the power load at any time.

Which energy storage systems will be dominated by PHS in 2035?

Lithium-ion batteries have the largest cumulative power capacity (240.5 GW), accounting for 81.4% of electrochemical energy storage. Thirteen provinces will still be dominated by PHS in 2035. In contrast, the remaining 17 provinces could be dominated by other new types of energy storage under the BAU scenario, as shown in Fig. 6.

What are the optimal energy storage configuration combinations?

The optimal energy storage configuration combinations under three preferences and seven combination scenarios were obtained by solving the influence of unit investment cost, power load, energy storage charging, discharging efficiency, and the proportion of installed RE capacity to the new power capacity of energy storage.

Can Bess-based PSO control frequency excursions?

Case-2: The simulation is carried out to study the performance of the frequency response by isolating one of the synchronous generators (G3) from the test system at t = 10 sec. From the frequency response, it can be concluded that the BESS-based PSO technique can also control the frequency excursions.
