The penetration of inverter-based distributed generators (DGs), which can control their reactive power outputs, has increased for low-voltage (LV) systems. The power outputs of DGs affect the voltage and power flow of both LV and medium-voltage (MV)

Indirect load control (ILC) is a method by which the customer determines load reduction of electricity by using a price signal. One of the ILCs is a time-of-use (TOU) tariff, which is the most commonly used time-varying retail pricing. Under the TOU

A strategy was developed for reactive power control of the line-commutated converters (LCCs) of hybrid multi-terminal high-voltage direct current (MT-HVDC) systems. In the conventional method, the reactive power outputs of hybrid MT-HVDC systems are
