Abstract: A communication system for an operation of an HVAC unit for a target space includes a thermostat, a communication hub, and a relay. The communication hub is configured to receive a user desired set point value from a remote control device and transmit the user desired set point value to the thermostat. The user desired set point value is for an operation of the HVAC unit. The relay includes a shielding unit and a transmitter. The shielding unit is configured to block a signal from the remote control device to reach the HVAC unit. The signal blocked by the shielding unit includes the user desired set point value. The thermostat is configured to receive the user desired set point value, adjust the user desired set point value based on measured temperature and/or humidity for the target space, and transmit the adjusted user desired set point value to the communication hub.

Abstract: A distributed energy management system includes a photovoltaic (PV) source, and a plurality of controllable loads in communication with the PV source. The plurality of controllable loads include a first controllable load including a first interactive plug associated with a first connected state timer and a first disconnected state timer, and a second controllable load including a second interactive plug associated with a second connected state timer and a second disconnected state timer. The PV source is configured to determine a maximum PV power, determine a difference between the maximum PV power and a current PV power, responsive to determining that the difference is less than or equal to a threshold power, set the reference AC voltage as a first voltage, and responsive to determining that the difference is greater than the threshold power, set the reference AC voltage as a second voltage greater than the first voltage.
