Multiple load deviation compensation method of distribution network under new power system

In the new power system, due to the popularity of new energy technologies such as distributed energy and electric vehicles, load changes are more diversified and unpredictable. Therefore, this paper proposes a compensation method for diversified load deviation of distribution network under new power system. The zero-crossing detection method is used to solve the signal frequency value, and the load zero position is solved according to the two points adjacent to the zero point. The actual signal frequency is obtained by sampling deviation error, the real-time signal frequency of the sampling period is solved, and the load compensation value is obtained according to the load value, thus completing the diversified load deviation compensation of the distribution network. Experimental results show that the proposed method can effectively calculate the load sampling deviation error under harmonic interference, and the compensation effect is obvious.
