Abstract: Methods and systems for mitigation of intermittent generation impact on electrical power system may be provided. A voltage of the power line may be monitored. A change in the voltage of the power line may be determined. A power output of an energy generation source connected to the power line may be altered based on the determined change in the voltage on the power line to compensate for the change in the voltage.
Abstract: Monitoring, command, control, and management of a street light may be provided. First, an amount of light may be determined. Next, a status of the street light may be determined based on the determined amount of light. Then, a current status of the street light may be determined. The current status may be compared with the determined status. Based on the comparison, the current status of the street light may be altered.
Abstract: Monitoring, control, and management of a plurality of street lights may be provided. First, a lighting policy comprising a list of local variables and a status of a street light corresponding to each of the plurality of local variables may be received. Next, a sensed local variable may be received. A status of the street light for the sensed local variable may be determined based on the lighting policy. A command may be generated, based in the determined status, for a controller associated with the street light.

Abstract: A microgrid and methods for managing the microgrid are disclosed. A microgrid controller may determine an amount of energy generated by each of a plurality of distributed energy resources connected to the microgrid. The microgrid controller may determine an amount of energy required to power each of a plurality of loads connected to the microgrid. The microgrid controller may alter, based on the determined amount of energy generated by the each of the plurality of distributed energy resources and the amount of energy required to power each of the plurality of loads connected to the microgrid, a status of at least one of the plurality of loads connected to the microgrid.

Abstract: A method for balancing power distribution in a direct current to direct current (DC to DC) power-conversion system is provided. The power-conversion system includes a plurality of channels that are connected to a load. The channels are also connected to corresponding power sources. The method, at a first channel, includes obtaining a first power, which is the maximum power of the power source connected to the first channel. Further, the method includes computing a reference power based on the power output of the channels. Furthermore, the method includes outputting the reference power when the first power is greater than or equal to the reference power, and outputting the first power when the first power is less than the reference power.
