A system of modules which control and measure energy usage at a building which are in communication with a software program executing on a remote server controlled by a third party. The third party said usage via the software program which communicates with the modules to modify energy usage and demand for energy and is responsible or liable for energy usage charges the building where the third party does not actually use the energy.

An example energy storage system and a related method are disclosed. In the energy storage system, a controller obtains information about user equipment, and then controls a converter and a battery group based on the information about the user equipment, to supply electric energy to an electric device or receive electric energy from a power sourcing device. In this way, the energy storage system can provide reasonable power scheduling, thereby improving utilization of the energy storage system.

A method and system are provided for controlling transfer switch operations in a power distribution system. The method and system involve monitoring an electrical parameter of an electrical signal from a first power source associated with supplying power to a load; determining whether the electrical parameter satisfies a parameter threshold; selecting to increment or decrement a count value in accordance with the determination; and responsive to determining that the count value satisfies a first count threshold, initiating a start signal to start operation of a second power source to supply power to the load. The electrical parameter can be voltage or frequency, or other parameter(s) from which a power quality of the electrical signal may be evaluated.
