POWER MANAGEMENT SYSTEM
A town storage battery power conversion device outputs an AC voltage to a distribution system during a power failure. Electric power generated by a solar cell installed in each consumer house is converted into an AC voltage by a solar cell power conversion device and output to a consumer premises distribution system to which a load is connected. In an autonomous operation during a power failure, an operation plan for a distributed power supply is updated in a cycle longer than a cycle of an operation plan for a town storage battery. In the autonomous operation, the town storage battery power conversion device changes an AC voltage frequency according to a difference between electric power output from the town storage battery and the operation plan. The solar cell power conversion device has a function of modifying a control target value for the solar cell according to the AC voltage frequency.

An electrical grid control system includes a number of load tap changers (2), a number of voltage regulators (4), a number of capacitor banks (6), a number of distributed generators (10), and a centralized control unit (12) structured to generate settings information for the load tap changers (2), the voltage regulators (4), the capacitor banks (6), and the distributed generators (10) based on forecasted data. The distributed generators (10) are structured to use the settings information and a distributed algorithm to control power provisioning from each of the distributed generators (10). The load tap changers (2), the voltage regulators (4), and the capacitor banks (6) are structured to adjust their settings based on the settings information and local voltage measurements.
Trending functions for predicting the health of electric power assets
A method for determining a dynamic rating for a conductive path includes using a sensor to measure a value for a load parameter and selecting a heating process associated with the load parameter. A rated temperature change is changed by removing temperature changes due to a heating process other than the selected heating process to produce an impaired rated temperature change. A thermal load percentage is determined from the impaired rated temperature change. The thermal load percentage and the measured value are then used to determine the dynamic rating for the load parameter. A method also includes measuring a temperature rise, a current, and a voltage on the conductive path multiple times. Using at least two basis functions and the multiple measured temperature rises, currents and voltages, the values for at least two variables are determined. Trends in each variable are determined to determine a condition of electric equipment.
ENERGY MANAGEMENT SYSTEM, INDEPENDENT SYSTEM, AND OPERATION METHOD OF INDEPENDENT SYSTEM
Regarding an independent system, a prediction value of charged/discharged power of a storage battery is calculated, based on a prediction value of generated power of a renewable energy power generator, a prediction value of demanded power of a control device, and a prediction value of demanded power of a load on an assumption that a power supply limit is applied to the load. Whether or not charge or discharge of the storage battery with charged/discharged power matching the prediction value of the charged/discharged power of the storage battery is possible is determined. The power supply limit is tightened when it is determined that the charge or discharge of the storage battery is not possible. A limit data indicating a detail of the power supply limit is output when it is determined that the charge or discharge of the storage battery is possible.
