RESOLUTION CALCULATING METHOD OF NODAL PRICE IN ELECTRIC POWER SYSTEM

摘要

PROBLEM TO BE SOLVED: To enable quantitative estimation concerning influence of power source or constraint upon nodal price and contribution of each factor to the nodal price, in electric power system.;SOLUTION: An optimal solution is obtained from an optimal solution equation to n-bus system. From the optimal solution, the nodal price is obtained. Constraint N estimating the charge positively is selected, and the nodal prices πp,k, πq,k and constituent elements are obtained. By substituting numerical values in the obtained elements of the nodal price, quantitative estimation concerning influence of generators G2, G22 and constraint upon the nodal price and the degree of contribution of each factor to the nodal price are enabled.;COPYRIGHT: (C)2001,JPO
