SYSTEMS AND METHOD FOR STABILIZER CONTROL
Abstract: a method, apparatus, system and computer program is provided for controlling an electric power system, including implementation of a voltage control and conservation (vcc) system used to optimally control the independent voltage and capacitor banks using a linear optimization methodology to minimize the losses in the eedcs and the eus. an energy validation process system (evp) is provided which is used to document the savings of the vcc and an epp is used to optimize improvements to the eedcs for continuously improving the energy losses in the eeds. the evp system measures the improvement in the eeds a result of operating the vcc system in the “on” state determining the level of energy conservation achieved by the vcc system. in addition the vcc system monitors pattern recognition events and compares them to the report-by-exception data to detect hvl events. if one is detected the vcc optimizes the capacity of the eeds to respond to the hvl events by centering the piecewise linear solution maximizing the ability of the edds to absorb the hvl event. the vcc stabilizer function integrates voltage data from ami meters and assess the state of the grid and initiates appropriate voltage control actions to hedge against predictable voltage risks.
