How does Peak-Valley electricity price spread affect electricity consumption?
By setting different peak-valley electricity price spread, the electricity consumption changes in the process of gradually increasing peak-valley electricity price differentials are studied. Renewable energy has the characteristics of randomness and intermittency.
Is the price of electricity higher in the peak period?
Specifically, it is stipulated that the price of electricity in the peak period under the optimized TOU electricity pricing is higher than the price of electricity in the weekday period, and the price of electricity in the weekday period is higher than the price of electricity in the valley period, as expressed in Eq. 9.
How are peak-to-Valley electricity prices optimized?
This period is divided into valley periods, and the rest of the period is divided into regular periods. According to the net load, the peak-to-valley electricity price periods are further optimized, and the optimized electricity prices for valley, flat, and peak periods are 0.28 RMB/kW·h, 0.42 RMB/kW·h, and 0.91 RMB/kW·h, respectively.
Can energy storage capacity be allocated in wind and solar energy storage systems?
This article studies the allocation of energy storage capacity considering electricity prices and on-site consumption of new energy in wind and solar energy storage systems. A nested two-layer optimization model is constructed, and the following conclusions are drawn:
