Power control apparatus and power control method using same

The present invention provides a power control method and a power control apparatus. The power control method of the present invention comprises the steps of: a first charge comparison step for receiving charge information of supplied power, and comparing the charge of the supplied power with a preset reference charge; and a second charge comparison step for comparing the charge of the supplied power with the preset lowest charge. Further, the method comprises the steps of: a first power quantity comparison step for confirming a stored power quantity within a power storage unit, and comparing the stored power quantity with a preset reference power quantity; and a second power quantity comparison step for comparing the stored power quantity with a preset power quantity demand. Further, the method comprises a control step for selecting one of externally supplied power and internally stored power as the usage power for the customer, through at least one of a charge comparison step and the power quantity comparison step. Particularly, the invention is characterized in that: if the charge of the supplied power is lower than the reference charge or the charge of the supplied power is higher than the reference charge in the first charge comparison step, the externally supplied power is selected as the usage power for the customer in case the stored power quantity is lower than the reference power quantity and the power quantity demand, through the first and second power quantity comparison steps; ; and if the charge of the supplied power is higher than the reference charge in the first charge comparison step, the stored power is selected as the usage power for the customer in case the stored power quantity is higher than the reference power quantity or the power quantity demand, through the first and second power quantity comparison steps.

Charge-discharge control system and method capable of prolonging service life of energy-storage battery

The invention discloses a charge-discharge control system and method capable of prolonging service life of an energy-storage battery. The system comprises a partition module, a power measurement module, an output intensity calculation module, a fuzzy controller, an SOC (state of charge) measurement module, an SOC deviation calculation module, a judgment module, a power correction module, an amplitude limiting module, a load classification module, a power supply insufficiency punishment cost calculation module, a cost comparison module, an annual average cost calculation module, a battery service life calculation module and a charge-discharge depth analysis module. When the SOC of the energy-storage battery approaches an overcharge warning area or an overdischarge warning area in the charging or discharging process, the charge-discharge control system and method are adopted, the charging power of the energy-storage battery is reduced, meanwhile, the SOC approaches an upper limit slowly but does not exceed the upper limit, so that the SOC of the energy-storage battery can be in a normal area to the largest extent, the cycle life of the energy-storage battery is prolonged, and the annual net earning off the system is maximized.

An excitation regulation and control system based on block chain network whole network construction cost control

InactiveCN109670701AReduce enthusiasm for investmentIncrease motivationPayment circuitsResourcesCost comparisonControl system
The invention discloses an excitation regulation and control system based on block chain network whole network construction cost control, which relates to the field of block chains and comprises a computing power acquisition module used for acquiring the current computing power value of the block chain network; an equivalent cost acquisition module which is used for acquiring input equivalent costof the block chain network according to the current computing power value; a cost comparison module which is used for comparing the input equivalent cost with a preset network construction cost value; and if the input equivalent cost is not matched with the preset network construction cost value, adjusting the excitation level of the block chain network to enable the input equivalent cost to be matched with the preset network construction cost value. According to the method, through the macroscopic regulation and control of the excitation level, the useless work of the honeycomb is avoided, the excessive social resources are prevented from being consumed, and the unit computing power profit is improved. The system effectively alleviates the problem that in the prior art, the block chain mining machine blindly follows the input of wind to cause malicious competence competition between the mining machines, and prevents overhigh accounting social cost caused by the competence competition.
