Patent number: 9678520Abstract: A method, apparatus, system and computer program is provided for controlling an electric power system, including implementation of an energy planning process (EPP) system which can be used to plan a voltage control and conservation (VCC) system applied to an electrical distribution connection system (EEDCS). The EPP system plans modifications to the EEDCS as a result of operating the VCC system in the “ON” state, in order to maximize the level of energy conservation achieved by the VCC system control of the EEDCS. The EPP system may also identify potential problems in the EEDCS for correction.Type: GrantFiled: February 28, 2014Date of Patent: June 13, 2017Assignee: Dominion Resources, Inc.Inventors: Melissa A. Peskin, Phillip W. Powell

Patent number: 9582020Abstract: 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.Type: GrantFiled: February 28, 2014Date of Patent: February 28, 2017Assignee: Dominion Resources, Inc.Inventors: Phillip W.
