<P>PROBLEM TO BE SOLVED: To solve problems related to a proposed technique requiring a complex measurement system that takes time for measurement, causing delay in the control and possibly failing to achieve stable control, the technique for compensating for output variation and the like, of a generator and the like, trying to maintain power quality of a self-supporting power supply system having a natural-energy generator and a large power load, the power quality that is difficult to maintain because the self-supporting power supply system has a small power capacity, making it susceptible to variation in the load and the like. <P>SOLUTION: Power storage equipment, comprising a secondary battery and a power converter, is provided with a power adjustment device to control active power and reactive power, thereby realizing simple, quick-response control. This enables adjustment of the power and frequency of a power supply system at predetermined values, thereby maintaining the stability and quality of the self-supporting power supply system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
