The service phase of the electrical connection to a customer endpoint device located within a power distribution system is determined by various techniques. At the feeder level, the system may be programmed to induce disturbances, thereby causing missed zero crossings at the customer endpoint devices. The pattern of these disturbances is a controlled one, designed specifically to avoid causing noticeable disruption even to sensitive devices, but to be unusual enough that it is statistically unlikely to be naturally occurring. The monitoring of the zero crossing information is used to determine the phase of the service line to the customer endpoint devices.

According to the SCADA measurement data or state estimation data at some continuous moments, the method utilizes recursive least squares solution to find a linear combination relationship between variation of measurement parameter to be estimated of nodes without PMU and variation of corresponding measurement parameter of nodes with PMU. Using the linear combination of relationship, the dynamic process of measurement nodes without PMU is estimated in real-time. The method provides high estimation precision and meets error requirements of engineering application.

Method and system for co-operative charging of electric vehicles

Номер: US20130141043A1
Автор: John Rossi
Принадлежит: John Rossi

A method and system provide for the cooperative charging of electric vehicles. By using power line communications, chargers of the electric vehicles who are serviced by the same distribution transformer can form self-contained local area networks due to the nature of power line communications (PLCs). Alternatively, or in addition to the PLCs, other communication networks, such as the Internet and local area networks, may be used as part of the communications infrastructure for the chargers. After the chargers of the electric vehicles are coupled to one another through power line communications or traditional communications networks, they can form a logical token ring network. According to this token ring network, a predetermined number of tokens can be assigned within the token ring network for permitting chargers with tokens to charge respective electric vehicles while chargers without tokens must wait until they receive a token to initiate charging.

An apparatus and a method for stabilizing an electrical power import from a power distribution system by way of at least one subscriber connected to the power distribution system via an electrical connection. An electrical power import anomaly when electrical power is imported by the respective subscriber from the power distribution system is identified using transmitted control messages, which are determined for the respective subscriber or originate from the respective subscriber. Once an electrical power import anomaly has been identified, power consumption units or power generation units are driven correspondingly. The apparatus effectively protects the power distribution system from third-party intervention or implementation errors which can bring about an unstable system response.

Power target values for the real power and reactive power at a transfer point between the energy distribution grid and an electrical energy transport grid are prescribed by a target value device. The target values are to avoid backward feed into the energy transport grid that could lead to malfunctions. The real and reactive power target values are compared with current values at the transfer point.

The disclosed method reconstructs a topology of an electrical distribution network. An ohmic matrix model is generated as a function of consumption measurements provided by smart meters in the network. A tree table of nodes to which the smart meters are connected is defined. A branch in exploration is defined in the table and the nodes of the branch meeting preestablished relations are entered in the table as a function of connection values derived from resistive quantities in the matrix model. One of the relations determines a junction of the branch in exploration with a branch already explored connectable to a root to which a distribution transformer of the distribution network is connected. The topology is reconstructed by iteratively proceeding with sequences of decreasing values derived from the resistive quantities. 1. Computer-implemented method for reconstructing a topology of an electrical distribution network having nodes to which smart meters are connected , the method comprising the steps of:(i) generating an ohmic matrix model of the distribution network as a function of consumption measurements provided by the smart meters, the ohmic matrix model having matrix terms indicative of resistive quantities between the nodes and a root to which a distribution transformer of the distribution network is connected;(ii) defining a tree table of the nodes; and (a) defining a new branch as branch in exploration in the tree table;', '(b) entering the node having the highest resistive quantity as terminal node of the branch in exploration in the tree table; and', '(c) entering in the tree table, in successive upstream positions from one another towards the root, all the nodes other than the terminal node meeting preestablished decision criteria as a function of connection values derived from the resistive quantities and, as other nodes are progressively entered for the branch in exploration, with said other nodes, one of the preestablished decision criteria ...

A prediction value calculator calculates a prediction value of an electricity fee based on the amount of electric power supplied from a commercial electric power source to electric equipment within an electricity fee calculation period. A selector selects, as a first-stage control, either one control of an electric power saving control for the electric equipment and a charge-discharge control in which the electric power supplied from the commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which the unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot. A controller executes the first-stage control selected by the selector when the prediction value calculated by the prediction value calculator is greater than a targeted value of the electricity fee.
