Abstract

According to one embodiment, an information processing device includes processing circuitry configured to calculate a first index based on a plurality of pieces of first prediction data on an amount of electric power generated by a first electric power generation resource and a penalty imposed when an amount of electric power supplied to an electric power system is insufficient or excessive for a first amount of electric power which corresponds to a planned value of electric power generation amount, the first index being an index related to a yield obtained in a case that the first amount of electric power is tentatively bid in a first market; and determine a second amount of electric power to be bid in the first market based on the first index.

First claim

The invention claimed is:

1. An information processing device comprising:
processing circuitry configured to:
acquire power generation results of a first electric power generation resource, wherein an amount of power generated by the first electric power generation resource varies depending on weather conditions, and wherein the power generated by the first electric power generation resource can be supplied to an electric power system;
generate a plurality of pieces of first prediction data on an amount of electric power generated by the first electric power generation resource based on the power generation results;
acquire, from an external server, penalty information of a penalty imposed when an amount of electric power supplied to the electric power system is insufficient or excessive for a planned value of electric power generation amount;
calculate, based on the first prediction data and the penalty information, a first index being an index related to a yield assuming that a first amount of electric power is tentatively bid for a day-ahead market and a third amount of electric power is tentatively bid for an intraday market; and
determine a second amount of electric power to be bid for the day-ahead market and a fourth amount of electric power to be bid for the intraday market based on the first index,

wherein
the planned value of electric power generation amount is a sum of amounts of electric power traded for the day-ahead market and the intraday market, and
the processing circuitry is further configured to:
fix an amount of electric power to be bid for the day-ahead market to the second amount of electric power, and calculate a second index being an index related to the yield assuming that the third amount of electric power is tentatively bid for the intraday market based on a plurality of pieces of fourth prediction data on the amount of electric power, generated by the first electric power generation resource, obtained after bidding for the day-ahead market is closed and before bidding for the intraday market is closed; and
re-determine, based on the second index, the fourth amount of electric power to be bid for the intraday market.

2. The information processing device according to claim 1 , wherein the processing circuitry
calculates the first index based on a plurality of pieces of second prediction data of a trade price of electric power for the day-ahead market and a plurality of pieces of third prediction data on a trade price of electric power for the intraday market,
fixes an amount of electric power to be bid for the day-ahead market to the second amount of electric power, and calculates the second index based on a plurality of pieces of fifth prediction data of an electric power price for the intraday market acquired after bidding for the day-ahead market is closed and before bidding for the intraday market is closed, and
re-determines, based on the second index, the fourth amount of electric power to be bid for the intraday market.

3. The information processing device according to claim 1 , wherein the processing circuitry determines, based on the first index, a bid amount ratio which is a ratio of the second amount of electric power and the fourth amount of electric power to be bid for the day-ahead market and the intraday market, respectively.

4. The information processing device according to claim 1 , wherein
the processing circuitry calculates a third index being an index related to the yield based on the bid amount ratio, and
the processing circuitry determines, based on the third index, a total amount of the second amount of electric power and the fourth amount of electric power to be bid for the day-ahead market and the intraday market, respectively.

5. The information processing device according to claim 1 , wherein
a balancing marked is a market in which supply of entire or part of an energy volume for which the bid is succeeded is made depending on whether an operation request is made from an electric power system operator,
the processing circuitry calculates a fourth index being index related to a yield in a case that a fifth amount of electric power is bid for the balancing market, and
the processing circuitry determines, based on the fourth index, a sixth amount of electric power to be bid for the balancing market.

6. The information processing device according to claim 5 , wherein the determiner determines, based on the fourth index, a bid price to be bid for the balancing market.

7. The information processing device according to claim 5 , wherein the processing circuitry simultaneously determines the sixth amount of electric power to be bid for the balancing market and the second amount of electric power to be bid for the day-ahead market.

8. The information processing device according to claim 7 , wherein the processing circuitry presents, on an interface for a user, as a candidate for an amount of electric power to be bid for the balancing market, the candidate including the fourth index and information indicating the sixth amount of electric power, and redetermines, based on information input through the interface, the amount of electric power to be bid for the balancing market.

9. The information processing device according to claim 1 , wherein the processing circuitry presents, on an interface for a user, a candidate for an amount of electric power to be bid for the day-ahead market, the candidate including the first index and information indicating the second amount of electric power and the fourth amount of electric power, and redetermines, based on information input through the interface, an amount of electric power to be bid for the day-ahead market.

10. The information processing device according to claim 1 , wherein
the first electric power generation resource is an electric power generation resource configured to generate renewable energy,
the amount of electric power supplied to the electric power system is acquired based on the first electric power generation resource and a second electric power generation resource capable of regulating an amount of generated electric power, and
the yield is calculated based on a total trade price of the second amount of electric power for the day-ahead market, a cost price of an amount of electric power procured from the first electric power generation resource, a cost price of an amount of electric power procured from the second electric power generation resource, and the penalty.

11. The information processing device according to claim 1 , wherein the processing circuitry determines at least one of the first to fourth indexes to be used among a plurality of indexes based on transition of a trade price in result data of past trading for the day-ahead market or a market different from the day-ahead market.

12. The information processing device according to claim 1 , wherein the amount of electric power generated by the first electric power generation resource and a trade price by which the second amount of electric power is traded for the day-ahead market have uncertainty.

13. The information processing device according to claim 1 , wherein the information processing device is an aggregator, and the aggregator sends bid data indicating the determined second amount of electric power to the day-ahead market and send bid data indicating the re-determined fourth amount of electric power to the intraday market.
