An electrical power distribution network, including a plurality of electrical power control apparatuses, each including : Signal conversion components in order to convert the received signal to have a desirable signal having a second fundamental frequency and characteristic voltage; and a controller that controls operation of the signal conversion components to determine an output voltage and output frequency of the electrical power control apparatus; electrical power generation components acting as sources of electrical power and electrical power consumption components acting as sinks of electrical power to at least some of the electrical power control apparatuses; and wherein the electrical power control apparatuses operate autonomously but are interconnected such that an output of each of the electrical power control apparatuses is connected to an input of at least one corresponding electrical power control apparatus and to one or more of the sinks and/or sources of electrical power so that the electrical power control apparatuses collectively maintain the voltages and frequencies of electrical power signals.
