Optimal Setting of Power and Frequency Parameters for Voltage-type Distributed Photovoltaic-Virtual Synchronous Generator Based on Transient Search Optimization
With the increasing penetration of distributed photovoltaic (DPV)
the proportion of traditional energy units continues to decline
resulting in a reduction of inertia and primary frequency regulation capabilities in power systems. Therefore
it is crucial to explore the frequency support capabilities of DPV in low-inertia systems. On this basis
first
this paper proposes an improved frequency active support method for voltage-type DPV-virtual synchronous generator (DPV-VSG) with variable reserve rate to enhance the system inertia
reduce the response delay
and improve the ability of DPV for active participation in system frequency support. Then
an optimal selection model for setting the power and frequency parameters based on the transient search optimization (TSO) algorithm is proposed to solve the optimal initial reserve power and best frequency regulation parameters of DPV
which improves the limitation of fixed photovoltaic initial reserve power. Finally
the proposed model is applied in a single-generator model and an actual distribution station area model with high penetration of DPV to verify its effectiveness.
