Systems and methods for managing power supplied over an electric power grid by an electric utility and/or other market participants to a multiplicity of grid elements and devices for supply and/or load curtailment as supply, each of which having a supply equivalence value associated with its energy consumption and/or reduction in consumption and/or supply, and wherein messaging is managed through a network by a coordinator using IP messaging for communication with the grid elements and devices, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.

Method and system for energy savings estimation resulting from power management system deployment

Methods, systems, and techniques for determining the confidence that predicted demand charge savings resulting from deploying an energy management system at a site will match actual cost savings. A processor obtains predicted demand charge savings resulting from deploying the energy management system at the site, and also obtains demand-related data describing at least two of load predictability, load shape, and battery capacity of the energy management system. The processor determines a confidence score representing the confidence that the predicted demand charge savings will result in view of the demand-related data, and displays the confidence score on a display for subsequent use by a user.

20220320898 · 2022-10-06 ·

A device uses linking rules to process and optionally update a hierarchical substation model of a power system substation. The linking rules determine to which substation object at a first hierarchy level substation objects at a further hierarchy level of the hierarchical substation model are to be connected.

System, method, and apparatus for electric power grid and network management of grid elements
11650613 · 2023-05-16 · ·

Systems, methods, and apparatus for smart electric power grid communication are disclosed in the present invention. At least one grid element transmits at least one registration message over an Internet Protocol (IP)-based network to at least one coordinator. The at least one coordinator registers the at least one grid element upon receipt of the at least one registration message. The at least one grid element automatically and/or autonomously transforms into at least one active grid element for actively functioning in the electric power grid. The at least one coordinator tracks based on revenue grade metrology an amount of power available for the electric power grid or a curtailment power available from the at least one active grid element.

Closed loop restoration

A system and method for restoring power in a closed-loop power distribution network. The network includes at least two power sources, at least one feeder and a plurality of switching devices positioned along the at least one feeder and being in communications with each other. The method performs a radial restoration process for restoring power and then determines that at least one of the sections is not receiving power after the radial restoration process has been performed. The method estimates power flow through each switching device and determines an available power capacity from each switching device. The method then determines if the unpowered sections can be powered by any of their neighbor and non-neighbor devices. The method virtually closes the switching devices to power the unpowered sections and updates the estimation of power flow through each switching device and determination of available power capacity from each switching device.

POWER GRID SYSTEM AND METHOD OF CONSOLIDATING POWER INJECTION AND CONSUMPTION IN A POWER GRID SYSTEM

A power grid system and a method of consolidating power injection and consumption in a power grid system. The power grid system comprises a power grid; at least one load connected to the power grid; a first meter configured for metering power imported from the power grid to the load; at least one intermittent power source connected to the power grid, a second meter configured for metering power generated by the intermittent power source; and a consolidation unit configured for associating readings from the first and second meters such that at least a portion of the power generated by the intermittent power source is offsettable with the power imported from the power grid to the load.

VALIDATING POWER NETWORK MODELS FOR MONITORING AND CORRECTING OPERATION OF ELECTRIC POWER NETWORKS
20170373535 · 2017-12-28 ·

This disclosure involves verifying that a power network model corresponds to an electric power network providing electrical power in a geographical area. For instance, a validation device computes a validation score for a power network model based on a connectivity score, an asset score, and a power-flow score. The connectivity score indicates connectivity errors in the power network model as compared to the power network. The asset score indicates power-delivery errors in the power network model with respect to power-consuming assets serviced by the power network. The power-flow score indicates power-flow calculation errors in the power network model with respect to voltage ranges for the power network. The validation score is repeatedly computed for iteratively updated versions of the power network model until a threshold validation score is obtained. The validated power network model is provided to a control system for identifying and correcting errors in the power network.

Alert presentation apparatus and alert presentation method

An alert presentation apparatus (EMS (200)) acquires the amounts of power consumed by loads connected to a system, and on the basis of the acquired power amounts, presents a load list including the power consumption of each load. This alert presentation apparatus (EMS (200)) presents the load list so as to reduce the frequency at which the loads that are on the load list change.

System, method, and apparatus for grid location

A computer system at a substation of an electrical grid examines on-grid communication channels and for very channel, the system compares and correlates a GLA signal provided by a downstream transmitter on that channel to a reference GLA signal. The channel that provided the signal with the best correlation is mostly likely the channel with the transmitter. Thus, the feeder and phase of the signal can be determined from the correlation of signals.
