6 FAQs about [Does solar power generation implement peak and valley ]

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.

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