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 enable the surplus supply capacity of distributed power supplies to be used effectively among a plurality of consumers each having the distributed power supply. SOLUTION: Power supply importance is preset to each load at a first consumer and a second one. Based on this power supply importance and the electrical distances between a first distributed power supply provided at the first consumer and each load, a first power supply precedence, which is power supply precedence to each load of the first distributed power supply, is determined. Furthermore, based on the electrical distances between a second distributed power supply provided at the second consumer and each load, a second power supply precedence, which is power supply precedence to each load of the second distributed power supply, is determined. Then, based on the power capacity that can be generated by the first distributed power supply and the capacity of each load, the precedence is determined for the loads to which electric power is supplied by the first distributed power supply. Based on power capacity that can be generated by the second distributed power supply and the capacity of each load, the precedence is determined for the loads to which electric power is supplied by the second distributed power supply. Then, the total surplus supply capacity supplied by the first and second distributed power supplies is calculated. Based on its remaining capacity, the precedence is determined for loads to which electric power is not supplied yet. COPYRIGHT: (C)2010,JPO&INPIT
