[Problem] As compared with the case where the apparent power in the electric line on the supply side is adjusted without supplying the current to the electric line closer to the power supply side than the distribution transformer, there is a reduction in the effect of the state in the electric line closer to the power reception side than the distribution transformer on the adjustment of the apparent power in the electric line closer to the power supply side than the distribution transformer.

[Solution] A power control system includes a device that receives power from an electric line of a distribution system via a distribution transformer, an acquisition unit that acquires electric line information on the electric line, and a control unit that causes the device to generate a current used for adjustment of apparent power in the electric line based on the electric line information acquired by the acquisition unit.

A system (and system controller) has powering of, and communication with, a set of fixtures using an AC cable having a power line (e.g. a mains live wire), a reference line (e.g. a mains neutral wire) and a data line. Fixtures are at different positions along the cable, each powered by the local voltage difference between the power line and the reference line. A system controller provides a data signal over the data line, wherein the data signal for a fixture is defined by the local voltage difference between the data signal on the data line and the reference line (or power line). In order to compensate for voltage drops, a compensation circuit adds a voltage offset waveform to the data signal which is dependent on the overall set of positions of the fixtures. This enables an increased number of fixtures and/or reach of the fixtures connected to the system controller.
