POWER GENERATION PLAN FORMULATION SYSTEM FOR SMALL-SCALE POWER SYSTEM AND METHOD THEREFOR

摘要

Provided are a power generation plan formulation system and a method therefor capable of drafting an optimum power generation plan for a small-scale power system by using power quality as a parameter. The power generation plan formulation system (10) is equipped with: a condition setting unit (11) for setting a time period for a power generation plan; a power quality condition setting unit (12) for setting power quality conditions by determining conditions regarding fluctuations in frequency and voltage; a power generation plan calculation unit (14) for determining operating costs by using the time period and the power quality set for the power generation plan; a power outage rate calculation unit (15) for calculating power outage rates in power outage periods; a risk calculation unit (16) for calculating power outage risks from the power outage rates, which have been calculated by the power outage rate calculation unit (15), by using a predetermined calculation formula; and an overall cost integration unit (17) for integrating overall costs by power quality by adding the power outage risks obtained by the risk calculation unit (16) and the operating costs obtained by the power generation plan calculation unit (14).
