Publication number: 20240127370Abstract: A dispatch optimization system and virtual power plant can be utilized and controlled in order to support the operations of a power distribution system. For example, upon determining an electrical need, the dispatch optimization system and/or virtual power plant may make an energy adjustment by allocating the energy adjustment among distributed energy resources of a fleet of distributed energy resources in order to achieve the energy adjustment. The dispatch optimization system and/or virtual power plant may determine the allocation among the distributed energy resources based on the economic costs and storage costs to use each distributed energy resource.Type: ApplicationFiled: August 30, 2023Publication date: April 18, 2024Applicant: Power Management Holdings (U.S.), Inc.Inventors: Michael K. Ruth, Duncan R. Brown, Andrew R. Gassner

Patent number: 11749992Abstract: A distribution feeder of an electricity grid comprises a substation and a plurality of nodes with at least one controllable reactive power resource. A method is provided for locally controlling delivery of electrical power along the distribution feeder, wherein for a feeder segment in the distribution feeder the method comprises: obtaining an actual voltage magnitude at an upstream node and at a downstream node of the feeder segment, and a real power value at the upstream node; setting a target voltage phasor at the downstream node as a value when a power flow across the feeder segment is maintained, and when equal reactive power is injected at the upstream and downstream nodes that consumes all the reactive power in the feeder segment; and adjusting operation of the at least one controllable reactive power resource so that the actual voltage magnitude at the downstream node moves towards a target voltage magnitude of the target voltage phasor.Type: GrantFiled: November 19, 2021Date of Patent: September 5, 2023Assignee: Power Management Holdings (U.S.), Inc.Inventors: Malcolm S. Metcalfe, Severin Nowak

Publication number: 20230155383Abstract: A system and a method for locally controlling delivery of electrical power along the distribution feeder by measuring certain electricity parameters of a distribution feeder line using a substation phasor measurement unit (PMU) electrically coupled to a substation distribution bus at a first node on the feeder line, and at least one customer site PMU electrically coupled to a low voltage end of a transformer at a customer site, wherein the transformer is coupled by a drop line to a second node on the distribution feeder line and the customer site is coupled by another drop line to the transformer, and by controlling at least one controllable reactive power resource and optionally a real power resource connected to the second node or at the customer site. Related apparatus, systems, articles, and techniques are also described.Type: ApplicationFiled: September 23, 2022Publication date: May 18, 2023Applicant: Power Management Holdings (U.S.), Inc.Inventors: Malcolm Stuart Metcalfe, Severin Nowak, John Todd Sankey, Eric Young

Publication number: 20220149619Abstract: A power distribution system includes an electrical utility and at least one virtual power plant. The virtual power plant can be utilized and controlled in order to support the operations of the electrical utility. Upon determining an electrical need, the utility instructs the virtual power plant to make an energy adjustment by a scheduled time. The virtual power plant allocates the energy adjustment among the distributed energy resources of its fleet in order to achieve the energy adjustment by the scheduled time.Type: ApplicationFiled: September 1, 2021Publication date: May 12, 2022Applicant: Power Management Holdings (U.S.), Inc.Inventors: Nima HARSAMIZADEH TEHRANI, Michael K.
