Problems solved by technology
The basic requirement for the stability of the power system when maintaining the balance of active and reactive power is the same for the power grid. However, due to the intermittent and fluctuating characteristics of distributed power sources, and the randomness of load changes, it brings a negative impact on the stable operation of the power grid. To challenge, cause the problem of large power fluctuations, at the same time the power quality in the microgrid is low, in addition, there is often a certain power shortage, and the system is unstable
