Abstract

This study evaluates the risk of battery State of Control (SOC) failure resulting from the difference between the activation rate assumed when creating the electricity market trading plan and the actual activation rate on the trading day. [Solution] The information processing device includes a creation unit that, before bidding on the spot market, creates an electricity market trading plan for trading electricity in the spot market and the supply and demand adjustment market based on a predicted value of the electricity price in the spot market on the trading day, a predicted value of the electricity price in the supply and demand adjustment market on the trading day, a first activation rate in the supply and demand adjustment market, and constraints including information on electricity trading and battery performance in the spot market and the supply and demand adjustment market; and an evaluation unit that, based on the electricity market trading plan and constraints, evaluates the SOC failure risk, which includes at least one of the inability to discharge the battery during electricity selling hours and the inability to charge the battery during electricity buying hours, when the activation rate is changed from the first to the second activation rate, and outputs the evaluation result.

Claims

1. Before bidding on the spot market, A creation unit creates an electricity market trading plan for trading electricity in the spot market and the supply and demand adjustment market, including information on the selling time, buying time, and the State of Charge (SOC) of the storage battery, based on the predicted value of the electricity price in the spot market on the trading day for which electricity is traded, the predicted value of the electricity price in the supply and demand adjustment market on the trading day for which electricity is traded, a first activation rate which is one of the rates at which adjustment power is activated to adjust the balance of electricity supply and demand in the supply and demand adjustment market, and constraints including information on electricity trading in the spot market and the supply and demand adjustment market and the performance of the storage battery. Based on the aforementioned electricity market trading plan and the aforementioned constraints, an evaluation unit evaluates the SOC failure risk, which includes at least one of the following when the activation rate is changed from the first activation rate to the second activation rate: the inability to discharge the battery during the electricity sales time and the inability to charge the battery during the electricity purchase time, and outputs the evaluation result. Information processing device including

2. An information processing apparatus according to claim 1, Before bidding on the aforementioned spot market, When the evaluation result indicates a risk of SOC failure, a calculation unit calculates the SOC failure time at which the battery becomes unable to discharge or charge when the electricity market trading plan is planned at the second activation rate, A modification unit modifies the electricity market trading plan based on the SOC failure time so that the risk of SOC failure is eliminated, An information processing device that further includes the following.

3. An information processing device having a processor and a memory device, Before bidding on the spot market, Based on the predicted electricity price in the spot market on the trading day for which electricity is traded, the predicted electricity price in the supply and demand adjustment market on the trading day, the first activation rate which is one of the rates at which adjustment power is activated to adjust the balance of electricity supply and demand in the supply and demand adjustment market, and constraints including information on electricity trading in the spot market and the supply and demand adjustment market and the performance of the storage battery, an electricity market trading plan is created for trading electricity in the spot market and the supply and demand adjustment market, including information on the time of sale, the time of purchase, and the State of Charge (SOC) of the storage battery. Based on the aforementioned electricity market trading plan and constraints, the system evaluates the SOC failure risk, which includes at least one of the following when the activation rate is changed from the first to the second activation rate: the inability to discharge the battery during the electricity selling time and the inability to charge the battery during the electricity buying time, and outputs the evaluation results. Information processing methods.

4. The information processing method according to claim 3, Before bidding on the aforementioned spot market, When the evaluation result indicates that there is a risk of SOC failure, the SOC failure time at which the battery becomes unable to discharge or charge when the electricity market trading plan is planned at the second activation rate is calculated. Based on the aforementioned SOC failure time, the electricity market trading plan is modified so that the risk of SOC failure is eliminated. Information processing methods.

5. Storage batteries and A control device for controlling the charging and discharging of the aforementioned storage battery, Information processing device, including, The aforementioned information processing device is Before bidding on the spot market, A creation unit creates an electricity market trading plan for trading electricity in the spot market and the supply and demand adjustment market, including information on the selling time, buying time, and the State of Charge (SOC) of the storage battery, based on the predicted value of the electricity price in the spot market on the trading day for which electricity is traded, the predicted value of the electricity price in the supply and demand adjustment market on the trading day for which electricity is traded, a first activation rate which is one of the rates at which adjustment power is activated to adjust the balance of electricity supply and demand in the supply and demand adjustment market, and constraints including information on electricity trading in the spot market and the supply and demand adjustment market and the performance of the storage battery. Includes an evaluation unit that evaluates the SOC failure risk, which includes at least one of the following when the activation rate is changed from the first activation rate to the second activation rate based on the aforementioned electricity market trading plan and constraints: the battery will not be able to discharge during the electricity selling time, and the battery will not be able to charge during the electricity buying time, and outputs the evaluation result. Information processing system.

6. The information processing system according to claim 5, The aforementioned information processing device is Before bidding on the aforementioned spot market, When the evaluation result indicates a risk of SOC failure, a calculation unit calculates the SOC failure time at which the battery becomes unable to discharge or charge when the electricity market trading plan is planned at the second activation rate, The modification unit further includes modifying the electricity market trading plan based on the SOC failure time so that the risk of SOC failure is eliminated.
