Economic viability of battery energy storage and grid strategy: …
Under the same pricing policy, the net incomes of different types of load patterns have little difference. The main reason is that the energy storage system supplies power outside in peak period and stores power in valley period. So the income is mainly affected by the peak-valley price variance, and the division way of peak-valley period.
