摘要： A voltage monitoring control device includes: a transceiver unit communicating with local voltage control devices adjusting a control amount of voltage control apparatuses that control a voltage on a power distribution line in a high-voltage system every second cycle based on a command value updated every first cycle; an indicatable-range updating unit determining an indicatable range, which is a range of reactive power indicatable to the local voltage control device, based on a control result received via the transceiver unit from the local voltage control device that controls a reactive-power-modified voltage control apparatus, the control result being a limit-value time or a limit-value-time ratio; and a reactive-power determination unit determining a reactive-power command value, which is a command value updated every first cycle based on the indicatable range and transmitted, via the transceiver unit, to the local voltage control device that controls the reactive-power-modified voltage control apparatus.

摘要： A method for optimizing consumption of reactive power in an electrical network includes a system for monitoring and adjusting electrical power supply, the system including an electrical generator, electrical loads, a power compensation system, an electric transmission line, an electro-digital processor and a remote-readable meter. The method further includes: measuring the dataset of the electrical loads via at least one remote-readable meter; collecting the dataset of the electrical loads and transmitting it to the electro-digital processor in order to establish data curves; calculating a power factor of the electrical loads; enabling reactive power compensation by setting the type and configuration of the compensation systems to be installed, when the calculated power factor has a value lower than or equal to a predefined threshold value; and compensating for reactive power by actuating the installed compensation systems.

摘要： Determining the number of loads associated with each phase in a three-phase electric power system. The loads can be associated with the consumption of electric power at a node, such as a metering device located at a facility. In one implementation, a central device that is connected to such nodes via a smart grid and a radio frequency mesh network can be leveraged to determine a phase in real time. For example, the central device can include a processor that executes one or more computer program modules which can cause a load tap changer having access to a distribution feeder in the smart grid to vary a voltage level supplied across each phase of the power system. Additionally, the central device can communicate with nodes in the mesh network to cause the nodes to perform voltage measurements and collect information related to such measurements.

摘要： A general decentralized voltage control scheme is proposed to coordinate the operation of DG, Voltage regulator and Capacitor banks. The present invention is based on placing a Remote Terminal Unit (RTUs) at each distribution generation (DG) and each at line capacitor. These RTUs being coordinated together through communication protocols form a multi-agent system. Novel decentralized system is proposed to estimate the voltage profile change as a result of injecting reactive power at the capacitor bus. Simulation results are presented to show the validity and the effectiveness of the present invention.
