6 FAQs about [Photovoltaic energy storage grid connection test]

Should a photovoltaic energy storage system be monitored in real time?

Therefore, in the case of no change in the operation structure of the grid, there is no need to monitor the natural frequency ωn of the photovoltaic energy storage system in real time, which is conducive to the promotion and application of the control strategy in the power system at this stage.

What is photovoltaic & energy storage system construction scheme?

In the design of the “photovoltaic + energy storage” system construction scheme studied, photovoltaic power generation system and energy storage system cooperate with each other to complete grid-connected power generation.

What is the optimal grid-connected strategy for energy storage power stations?

In this section, energy storage power stations are considered and the optimal grid-connected strategy based on load fluctuation is adopted. The maximum charge and discharge power of energy storage power stations is 150 MW. The operating results of the energy storage power station are shown in Fig. 7.

How can a photovoltaic energy storage system provide efficient frequency support?

To ensure that the photovoltaic energy storage system provides efficient frequency support and power oscillation suppression, the virtual inertia and virtual damping parameters of the VSG should be coordinated based on system frequency safety and damping ratio constraints.

What is the minimum inertia demand of a photovoltaic energy storage system?

In a regional power grid, based on the operating conditions and system model, if the estimated disturbance power does not exceed 10 % of the total capacity, i.e., Δ Pd = 0.1pu, the minimum inertia demand of the photovoltaic energy storage system can be obtained in this case, when the maximum allowable rate of change of frequency is set.

How to estimate the cost of a photovoltaic & energy storage system?

When estimating the cost of the “photovoltaic + energy storage” system in this project, since the construction of the power station is based on the original site of the existing thermal power unit, it is necessary to consider the impact of depreciation, site, labor, tax and other relevant parameters on the actual cost.
