Abstract: An electrical power system includes an electrical power distribution network and a control device configured to regulate at least one attribute of said electrical power system. The electrical power system further includes a processor coupled to the control device configured to identify an out-of-bound condition on said electrical power distribution network at a first time. The out-of-bound condition is associated with the at least one attribute. The processor is also configured to determine a trend for the at least one attribute at a second time that is later than the first time after a predetermined delay time elapses. The trend indicates a direction away from at least one of a predetermined range and a predetermined value. The processor is also configured to transmit a control action to said control device based at least in part on the trend.

Abstract: Systems and methods for regulating the voltage at a point of interconnection of a renewable energy plant, such as a solar plant, with a grid are provided. A voltage signal indicative of the voltage at the point of interconnection can be received and filtered with a high pass filter to generate a filtered error signal. The high pass filter can block components of the voltage signal at a frequency less than a threshold frequency. A reactive power command for the renewable energy plant can be generated based on the filtered error signal. One or more inverters of the renewable energy plant can be controlled to output reactive power based on the reactive power command. A rejection module can be implemented to prevent adverse interaction with other voltage control devices. In addition, a reset module can be implemented to preserve dynamic reactive power range of the inverters.
