The embodiment of the invention discloses an electric parameter calibration method and device, electronic equipment and a storage medium. Comprising the steps of obtaining a calibration initial value of an included angle between voltage and current output by a measured measuring instrument; respectively calculating an active power initial calibration value corresponding to the calibration initial value and an active power standard value corresponding to the angle standard value, and calculating an initial calibration deviation value between the active power initial calibration value and the active power standard value; determining an expected deviation value between an active power expected value corresponding to the included angle expected value and an active power standard value; calculating the ratio of the initial correction deviation value to the expected deviation value, wherein the ratio is a phase correction value; obtaining a phase compensation coefficient according to a mapping relation between the
