A grid-independent micro-combined heat and power system supplies heat and electricity to a building or a small number of buildings and can operate completely independently of a central-type electrical power grid. The system includes a variable speed liquid-cooled engine and a liquid-cooled generator that is configured to output an electrical supply of between approximately between 0.5 kW and 40 kW, a coolant loop, and a water circuit. The coolant loop heats a liquid using claimed heat from the genset to heat water that can be utilized as a domestic hot water source for cooking or cleaning or for a hot water source for heating. The speed of the engine may be controlled to control the output of the genset to meet prevailing electrical loads. The system may be part of a microgrid incorporating several such systems that are in electrical communication with one another and that collectively supply electrical power and heat to from a few buildings to about one hundred buildings.

A load control system may include multiple control devices that may send load control messages to load control devices for controlling an amount of power provided electrical loads. To prevent collision of the load control messages, the load control messages may be transmitted using different wireless communication channels. Each wireless communication channel may be assigned to a load control group that may include control devices and load control devices capable of communicating with one another on the assigned channel. A control device may send load control messages to a load control device within a transmission frame allocated for transmitting load control messages. The transmission frame may include equal sub-frames and load control messages may be sent at a random time within each sub-frame. Control devices may detect a status event within a sampling interval to offset transmissions from multiple control devices based on detection of the same event.
