Title:
CVR CONTROL METHOD FOR ENERGY REDUCTION IN LOW VOLTAGE DISTRIBUTION NETWORK, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/063464
Kind Code:
A1
Abstract:
The present invention relates to a CVR control method in an energy management system, the method comprising the steps of: obtaining a plurality of pieces of measurement data from a plurality of consumer loads linked to a distribution network; estimating a ZIP coefficient for each load on the basis of the obtained plurality of pieces of measurement data; calculating a system load of the distribution network on the basis of the estimated ZIP coefficient for each load; and calculating a reactive power command value for each of distributed power supplies by using an optimization algorithm considering the calculated system load of the distribution network.
