考虑不平衡责任的奖罚性电能计量新方法
A new method of rewarding and punishing electric energy metering considering unbalanced responsibility
Taking the negative sequence electric energy generated by asymmetric load in power grid as the research object, and aiming at the reasonable metering of electric energy, the influence of negative sequence power generated by asymmetric load on the metering of electric energy is first analyzed. In this paper, a new method of rewarding and punishing electric energy metering considering unbalanced responsibility is proposed for the existing problems of active power metering methods. Secondly, the power decomposition method is used to decompose the negative sequence active power at the PCC point into the utility side and the customer side negative sequence active power. Thirdly, based on IEEE Std.1459-2010 power theory, a new index of quantitative assessment of unbalanced responsibility, negative sequential apparent power, and a specific calculation method of unbalanced responsibility are given, and a reward and punishment coefficient reference value is set according to the unbalanced responsibility value. Finally, a concrete simulation example is designed to verify that the new method of rewarding and punishing electric energy metering is more fair and reasonable in the grid with serious negative sequence pollution.
