Publication number: 20130229149Abstract: Techniques for controlling dispatch of electric vehicles (EVs) to perform vehicle-to-grid regulation of power of an electric grid are presented. An aggregator component can individually control transitioning respective EVs of a set of EVs between a charging state and a not-charging state. The aggregator component includes a dispatch controller component (DCC) that can employ a defined dispatch algorithm for EVs to facilitate enabling the DCC to perform unidirectional regulation. The DCC can switch EV charging stations on and off using remote switches to meet a system regulation signal. The DCC can use the dispatch algorithm to make determinations regarding which EV to switch using charging priorities, in accordance defined power regulation criterion(s). The aggregator component can reduce communication signals used to adjust dispatch by sending switching signals to only those EVs of the set of EVs that are changing their charging state at a given time.Type: ApplicationFiled: June 7, 2012Publication date: September 5, 2013Applicant: ALSTOM GRIDInventor: Eric Sortomme

Publication number: 20120316689Abstract: The subject specification comprises enhanced communication infrastructure for a multi-tier hierarchical smart distribution grid (SDG). The SDG comprises a specified number of distribution network node controller (DNNC) components employed to desirably control communications and power distribution between respective tiers of the SDG to facilitate efficient power distribution. When communication between the a DNNC in one tier and another DNNC in another tier, is desired, the DNNC can identify available communication channels and respective communication conditions of the available communication channels, and can dynamically select a subset of available data and preferred communication channel, based at least in part on predefined control criteria, to control data transmission loads in the network and facilitate real time control of the SDG. Data can be communicated via the selected communication channel.Type: ApplicationFiled: June 8, 2011Publication date: December 13, 2012Applicant: ALSTOM GRIDInventors: Ethan Clair Boardman, Sumit Roy, Subrahmanyam Saraswati Venkata

Publication number: 20120316688Abstract: Aspects of a multi-level electrical distribution control system associated with an electrical distribution grid are disclosed. Coordination between the multi-level control system, the electrical distribution grid and an electrical transmission system can provide improved utilization of energy within the electrical distribution grid. Further, dynamic reconfiguration of the electric distribution grid can improve reliability of the electric distribution grid and can provide additional energy utilization pathways to reduce demand on the electrical transmission system. Moreover, improved control of the topography and energy utilization of the electrical distribution grid can improve forecasting for development of the electrical transmission system.Type: ApplicationFiled: June 8, 2011Publication date: December 13, 2012Applicant: ALSTOM GRIDInventors: Ethan Clair Boardman, Subrahmanyam Saraswati Venkata

Publication number: 20120316696Abstract: Aspects of a multi-level electrical distribution control system associated with an electrical distribution grid are disclosed. A multi-level control system provides a non-flat topography for electrical distribution grid control. A hierarchical structure can be employed in the topography of the control system. Further, tree and mesh network structure, among others, can be employed in the topography of the control system. These rich topographies can provide for closed loop control at each level of the control system, improved reliability of the control system through redundant topographical network structures, and desirable data handling features that can reduce data congestion and computing costs by distributing data handling, processing, and control across the levels of the control system.Type: ApplicationFiled: June 8, 2011Publication date: December 13, 2012Applicant: ALSTOM GRIDInventors: Ethan Clair Boardman, Subrahmanyam Saraswati Venkata

Publication number: 20120316691Abstract: The subject specification comprises enhanced power system balance control for a multi-tier hierarchical electrical distribution network (EDN). The EDN comprises a specified number of distribution network node controller (DNNC) components employed to desirably control power system balance, data communications, and power distribution between respective tiers of the EDN to facilitate efficient power distribution. In each tier, a power system balance component (PSBC), associated with a DNNC component, can monitor power system balance, such as load phase balance, associated with multi-phase power distribution for its tier, and detect power system imbalances in that tier. A power balance correction action can be identified and executed (e.g., automatically) in response to the detected power system imbalance to rectify the imbalance, wherein the correction action can include dynamic switching of loads between phases and/or filtering of the power signal.Type: ApplicationFiled: June 8, 2011Publication date: December 13, 2012Applicant: ALSTOM GRIDInventors: Ethan Clair Boardman, Subrahmanyam Saraswati Venkata

Publication number: 20110282508Abstract: The subject specification comprises a generalized grid security platform (GGSP) that can control power distribution and operations in a power transmission and distribution grid (PTDG) in real or near real time. The GGSP can receive data from one or more data sources, including a PMU(s) or an IED(s), which can obtain power system related data and provide at least a portion of such data to the GGSP at a subsecond rate. The GGSP can correlate data from the data sources based at least in part on a temporal, geographical, or topological axis. The GGSP can analyze the data, including performing predictive analysis, e.g., via simulation, root cause analysis, post mortem analysis, or complex event processing, when desired, to facilitate identifying a current or predicted future state of the PTDG, a cause or source of an abnormal condition, or a remedial action execution plan, new operation or maintenance guidance, etc.Type: ApplicationFiled: May 11, 2011Publication date: November 17, 2011Applicant: ALSTOM GRIDInventors: Eric Goutard, Spero Mensah
