  • Publication number: 20230155383
    Abstract: 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.

  • Publication number: 20200295564
    Abstract: A first energy converter that can consume a first physical energy form of a first energy delivery network can be controlled to produce a second physical energy form of a second energy delivery network and inject the second physical energy form into the second energy delivery network. A second energy converter that can consume the second physical energy form of the second energy delivery system can be controlled to produce the first physical energy form of the first energy delivery network and inject the first physical energy form into the first energy deliver network. The controlling of the first energy converter and the controlling of the second energy converter can be coordinated. Related apparatus, systems, techniques and articles are also described.

  • Patent number: 9762087
    Abstract: An apparatus for providing Ancillary Services to an ISO controls multiple controllable resources over a network in a cost effective manner. The apparatus comprises a central server computer and multiple controllers communicative with the central server computer over a network. Each controller is located at a resource site and controls one or more resource devices. The central server computer has a memory with a program which executes the following operations: receives a services request signal from the ISO such as a Ancillary Services request, which requests a change in power consumed or supplied by the resources on the network; calculates the lowest cost means of delivering the requested Ancillary Services request; and sends setpoint control signals to the controller at each resource site where a change is needed, requesting a change in the operation of each resource device.

  • Publication number: 20140375472
    Abstract: The present disclosure is directed at methods, systems, and techniques for measurements and, optionally, auditing of resource meters such as electricity meters. Each of multiple site aggregation units receive measurements from resource meters. Each of the site aggregation units generate a site aggregation digest that substantially uniquely identifies the resource measurements, stores these digests, and aggregates the resource measurements into site aggregation data that is sent to a central aggregation unit. The central aggregation unit generates a central aggregation digest that substantially uniquely identifies the site aggregation data, stores this digest, and aggregates the site aggregation data into central aggregation data that is sent to a resource provider with the central aggregation digest. When auditing is to be performed, the site and central aggregation digests can be used to verify the authenticity of the resource measurements and the site aggregation data, respectively.
