6 FAQs about [Use peak and valley electricity to store energy]

Do energy storage systems achieve the expected peak-shaving and valley-filling effect?

Abstract: In order to make the energy storage system achieve the expected peak-shaving and valley-filling effect, an energy-storage peak-shaving scheduling strategy considering the improvement goal of peak-valley difference is proposed.

Does peak-valley spread affect peak-shaving of the power grid?

Although wider peak-valley spread promotes cost-savings for LEM participants, the effects on peak-shaving of the power grid is marginal. This is because the peak-valley mechanism is still insufficient to identify all potential spikes in power supply, so the storage and reserve capacity resources cannot reach the efficient allocation.

Does storage reduce the Electricity Feed-in of prosumers?

The presence of storage further reduces the electricity feed-in of prosumers, although there is only a slight peak reduction due to the insufficiency of peak-valley tariffs. By reducing electricity feed-in, LEM and LEM + storage contribute immensely towards alleviating the transmission pressure and volatility of the grid. Fig. 11.
