The technical and economic selection method of energy storage power supply for grid frequency regulation is studied. First, the technical and economic indicators of different forms of energy
Primary frequency regulation (PFR) is a crucial operating condition for Power System Stabilizers (PSPs) to achieve frequency modulation. Its effectiveness is significant to the stability of power system frequency.
The effectiveness of PSPS in regulating system frequency is verified in actual generation systems such as hydro-wind [8], hydro-photovoltaic [9], and hydro-wind–solar hybrid power systems [10]. The flexibility and reliability of PSPS in this regard are also confirmed.
To measure the power regulation performance and operation stability of a variable, four indicators were introduced: standard deviation of power difference and power delay for power regulation performance, and settling time and overshoot of frequency for frequency stability.
The advantages of F-VPSP in rapid and stable frequency regulation are revealed in Figure 8 b. As Tw increases from 2.7 s to 3.3 s, the settling time increases from 15.4 s to 27.3 s and the maximum of frequency deviation rises from 0.143 Hz to 0.361 Hz.
The maximum frequency deviation for F-VPSP is 0.361 Hz. Although F-VPSP has superior primary frequency regulation performance, similar oscillation is observed in the rotational speed of a pump-turbine in VSU, with an amplitude of 0.032 pu and frequency of 0.04 Hz.
The sensitivity index of the DFIM frequency controller is the highest for both indicators, indicating that VSU (Variable Speed Unit) is more crucial for the PFR performance of F-VPSP (Flexible-Variable Power System with Supervisory Control) system. The effects of water inertia and pump-turbine parameters on regulation performance are more noticeable, while their impact on system stability is minimal.
