Calculation of Nodal Price for Nonoptimal System by Imaginary Constraint Condition

가상제약조건에 의한 비최적 현재운전계통의 모선가격산정

This Paper proposes the new method of Nodal Price calculation on nonoptimal condition of power system. It uses Power Flow instead of Optimal Power Flow. We propose a idea of imaginary constraints at the first. And the proposed method is applied to IEEE-30 and results show the effectiveness of the method.
