Electric power demand/supply planning apparatus and method for the same
First Claim
1. An electric demand/supply planning apparatus, comprising:
- an initial demand/supply plan creating section which creates an initial demand/supply plan of a controllable electric power source in an electric power system into which a natural energy electric power source is introduced, based on a demand predicted value, a predicted value of a natural energy electric power source power generation output amount, and electric power source equipment data;
a demand/power generation amount probability density distribution creating section which creates a probability density distribution of a demand and a probability density distribution of a natural energy electric power source power generation output amount at every predetermined processing time, by using fluctuation bands of the demand and of the natural energy electric power source power generation output amount which are set in advance;
an economic load dispatch calculating section which calculates an output allocation to minimize a total fuel cost of the controllable electric power source based on the initial demand/supply plan created in the initial demand/supply plan creating section, the probability density distribution of the demand and the probability density distribution of the natural energy electric power source power generation output amount which are created in the demand/power generation amount probability density distribution creating section, thereby to create a prediction distribution of a power generation output of the controllable electric power source; and
a display section which displays the prediction distribution of the power generation output of the controllable electric power source created in the economic load dispatch calculating section.

Abstract
An electric power planning apparatus is provided. The apparatus has an initial plan creating section, a generation amount probability density distribution creating section, an economic load dispatch calculating section, and a display section. The initial plan creating section creates an initial plan based on a demand predicted value, a predicted value of a natural energy electric power source power generation output amount, and electric power source equipment data. The generation amount probability density distribution creating section creates a probability density distribution using fluctuation bands of the demand and of the natural energy electric power source power generation output amount. The economic load dispatch calculating section calculates an output allocation based on the initial plan and the probability density distribution to create a prediction distribution of a power generation output of the controllable electric power source. The display section displays the prediction distribution.
