For example, the national power grid implements tidal power prices (step power prices, peak staggering power prices) for users, and the power prices for general industry and commercial enterprises are defined as follows, and the power prices are divided into four stages:
The time is divided into four periods:
In terms of time periods, peak periods cover peak periods, which exist in July August each year. The energy can be stored in the valley section and released in the peak period, so that the consumption reduction, synergy and operation cost are reduced. The optimal time period for reducing the electricity cost is a high peak time period, and the parallel section has smaller cost reduction amplitude, but can also be used in the parallel section (namely, the parallel section can release energy of the energy accumulator) under the condition of surplus electric quantity. The factor of cost reduction is determined by the magnitude of the load power and how much energy is stored by the energy storage device, and the electric quantity stored by the energy storage device is slightly larger than the load power to work for 8 hours, so that the cost reduction can be maximized. Through simulation experiments, the DC48V200AH energy accumulator can work for 10 hours under the load of 1200W, and the electricity consumption is 12 degrees, so that the cost can be reduced by 12 RMB. If the DC load is 3000W, the energy is released for 8 hours in a high peak period, the power is used for 24 degrees, and the cost is reduced by 24 yuan. The cost is reduced by 24 yuan a day, and the cost is reduced by 8760 yuan a year. In addition, the service life of the general base station and machine room lead-acid battery is 5 to 6 years, the value of a group of 48V200AH batteries is about 15000 yuan, and because the base station and machine room lead-acid battery (i.e. an energy accumulator) is extremely low in use frequency as a standby power supply, the number of charging and discharging times is very small, the service life of the lead-acid battery is reduced, the service frequency of the lead-acid battery can be greatly improved by adopting the scheme, and the service life can be doubled and is about 10 years. The original operation mode needs to pay 30000 yuan for 10 years, and after adopting the scheme, the cost of the battery is saved by about 1500 yuan for 10 years because the cost of the battery is paid by about 15000 yuan for 10 years. The electricity charge cost is reduced by about 8760 yuan for one year by combining the base station, the battery cost is reduced by 1500 yuan, and the total cost is reduced by 10260 yuan.
