摘要： PROBLEM TO BE SOLVED: To provide a power receiving point power operation controller and a control method for small-scale power system, which generate an interpolated power receiving point power target value changing not stepwise but smoothly, and correctly maintains and controls costs in accordance with an operation plan and an optimal operation to environmental influence based on the target value. SOLUTION: The power receiving point power operation controller causes receiving power and/or received electric energy from a commercial power system to follow the target value for electricity demand of the small-scale power system in which a distributed power supply links to the commercial power system. A prescribed value of the power receiving point power target value is computed for a setting period for each section from each time to the next time in each setting time by an operation plan means 1. On the basis of the computed value, a receiving power target value interpolation means 3 computes an interpolated power receiving point power target value so that a target value of each section during the setting period, if a change direction of the target value from the preceding section for the own section and a change direction of the target value to the subsequent section are identical, will vary in magnitude in the own section and a time integral value in the own section will have a same value as a time integral value in a section for the same target value.

摘要： PROBLEM TO BE SOLVED: To provide a power quality evaluation system capable of estimating the cause of harmonics. SOLUTION: The power quality evaluation system includes a harmonic component computing means, a database, and a degree of influence computing means. The harmonic component computing means computes the harmonic component of an electrical physical quantity, with respect to each of points of measurement based on the electrical physical quantity that includes at least either the current or the voltage measured at one or more points in a power system. The database stores the harmonic components of multiple harmonics generating devices that are assumed to generate the harmonics. The degree of influence computing means approximates each harmonic component computed by the harmonic component computing means by a total value obtained by adding a weighting factor to the harmonic components of the harmonics generating devices stored in the database, and the componentof influence computing means can thereby estimate the cause of a harmonics generating device that serves as a source of harmonics, based on the approximated weighting factor.
