6 FAQs about [Photovoltaic energy storage peak load regulation]

Can energy storage allocation and Line upgrading reduce peak load and Peak-Valley difference?

In this paper, a comprehensive configuration strategy of energy storage allocation and line upgrading has been proposed. This strategy can reduce the peak load and peak-valley difference caused by the rapid development of loads and the integration of a high proportion of PVs in distribution networks.

What causes peak load and Peak-Valley difference of PV power?

The peak load and peak-valley difference of the net load power (load power—PV power) increase because of the increase in PV proportion, increasing load demand in distribution networks, uncertainty in PV power output and load demand and timing mismatch between the peak PV output and the peak load demand.

How to reduce peak load and Peak-Valley difference in distribution networks?

In this paper, a comprehensive configuration strategy is proposed to reduce the peak load and peak-valley difference in distribution networks. The strategy includes the allocation of centralised energy storage in transformer stations, the allocation of decentralised energy storage on lines and the upgrading of distribution lines.

Do power supply side methods reduce peak load regulation?

Power supply side methods can effectively improve the consumption of DGs and reduce the peak load regulation problem in power systems. However, the peak load and large peak-valley difference in distribution networks caused by the integration of high proportion DGs are not reduced in refs. [8, 9].

Does energy storage demand power and capacity?

Fitting curves of the demands of energy storage for different penetration of power systems. Table 8. Energy storage demand power and capacity at 90% confidence level.

How do photovoltaics affect the power grid?

The rapid development of photovoltaics (PVs) and load caused a significant increase in peak loads and peak-valley differences in rural distribution networks, which require load peak shifting and line upgrading. Large peak-valley differences also bring challenges on the safe operation of the utility power grid.
