Description

The present invention is suitable for application to, for example, a bidding support system.

In Japan, electric power system reform is underway, and the final stage will be the separation of electric power transmission. As a result, the power transmission and distribution business and the power generation / retail business of general electric power companies (electric power system operators), which have conventionally provided power in a vertically integrated business form, will be separated (delivery power separation). The power transmission and distribution business will be carried out by the general power transmission and distribution business operator, and the power generation / retail business will be carried out by the power generation business operator, the retail electric power business operator, or the power generation / retail business operator that integrates both.

In addition, a supply and demand adjustment market will be created for the purpose of reducing the procurement cost of the adjustment power necessary for adjusting the supply and demand balance and controlling the frequency and promoting wide-area power interchange in accordance with the separation of power transmission and demand. In this supply and demand adjustment market, short-term supply and demand adjustment ability is traded through the market, and the power generation company sells and bids the adjustment power (adjusted power supply) to the market, and the general power transmission and distribution business operator buys and bids on the market. By doing so, it is a market transaction.

Here, since the adjusting power is used for the supply-demand balance adjustment and frequency control after the gate close (GC), the supply-demand adjustment market uses electric power energy as a product whose main purpose is to adjust the supply-demand balance up to the GC. It will be established as a separate market from the Japan Electric Power Exchange (JEPX) that handles it.

In line with the above situation, general electric power companies have traditionally used their own power sources to control frequencies and adjust the balance between supply and demand within the area under their jurisdiction (see Patent Document 1), but the establishment of a supply and demand adjustment market has been established. As a result, general power transmission and distribution companies will be required to procure and operate cheaper adjustment power over a wide area through the market to reduce adjustment costs.

On the other hand, the power generation / retail business forecasts the power demand in advance and adjusts the supply according to the prediction (see Patent Document 2). However, due to the establishment of the supply / demand adjustment market, the power generation / retail business has become By strategically providing the company's adjusting power (adjusted power source) to the market, it will be required to operate the most economical generator that maximizes profits.

However, since the supply and demand adjustment market is a newly created market, there is no technology that can appropriately determine the necessity of bidding, and such technology is required.

The present invention has been made in consideration of the above points, and an object of the present invention is to propose a bidding support system capable of appropriately determining the necessity of bidding.

In order to solve this problem, in the present invention, the power demand forecasting unit that predicts the power demand in the area under the jurisdiction of the company, the supply capacity management unit that manages the supply capacity in the area, and the free capacity of each interconnection line are used. Based on the system operation information prediction unit to be predicted, the power demand predicted by the power demand prediction unit, the supply capacity managed by the supply capacity management unit, and the free capacity predicted by the system operation information prediction unit. Therefore, we have established an adjustment power transaction price forecasting department that predicts the transaction price of the supply and demand adjustment market.

According to the above configuration, the supply and demand adjustment market is based on the power demand predicted by the power demand forecasting unit, the supply capacity managed by the supply capacity management department, and the free capacity predicted by the grid operation information forecasting department. The transaction price can be predicted.

According to the present invention, it is possible to realize a bidding support system for the supply and demand adjustment market.

It is a figure which shows an example of the processing procedure which concerns on the calculation of the bid amount by the 3rd Embodiment.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, for example, a general power transmission and distribution business operator can reduce adjustment costs by procuring adjustment power from the supply and demand adjustment market and operating it over a wide area, and a power generation / retail business operator can use its own adjustment power (adjustment power supply). We will explain the technology (configuration) to support the planning of adjustment power trading in order to realize the most economical generator operation that maximizes profits by strategically providing it to the supply and demand adjustment market.

In the application of this technology to general power transmission and distribution business operators, the required amount of adjustment power in the own area is calculated, and the necessity of bidding to the supply and demand adjustment market is determined from the result, each forecast and actual information. As a result, the general power transmission and distribution business operator can procure the market only when, for example, the cost can be reduced by procuring and operating the adjustment power over a wide area.

In the application of this technology to power generation / retailers, the necessity of bidding in the supply / demand adjustment market is determined by comparing the calculation result of the amount of adjustment power that can be provided by the company with the price forecast value of energy transactions. As a result, power generation / retailers can, for example, trade in a market where their own adjusting power (adjusted power source) can be sold at a higher price.

In addition, power generation / retailers can maximize profits by strategically providing their own adjustment power (adjusted power supply) to the market.

(2) Second Embodiment Even after the establishment of the supply and demand adjustment market, the general power transmission and distribution business operator, as a power system operator, in order to maintain stable operation of the power system, the amount of power demand and the power from the generator. It is necessary to match the supply amount. In particular, in recent years, there is a problem that a large amount of renewable energy represented by solar power generation and wind power generation is being introduced into the grid, and to solve this problem, a supply and demand control function that takes into account fluctuations in the output of renewable energy. Has been devised. For example, a technique capable of improving frequency control performance by separating fluctuations in the output of natural energy and fluctuations in demand for a general load is disclosed (see Japanese Patent Application Laid-Open No. 2014-204757).

By using the technique described in Patent Document 1, it is possible to optimize the supply-demand balance adjustment and frequency control by utilizing the power source owned by the company in response to the increase in output fluctuation due to the increase in renewable energy. However, in a situation where supply and demand balance adjustment and frequency control over a wide area are required by utilizing the adjustment power procured in the supply and demand adjustment market, it is difficult to truly reduce the adjustment cost by the method as in Patent Document 1. Is.

In this embodiment, an example will be described in which the supply and demand adjustment market bid processing device 100 is applied to the central power supply command center system 110 of a general power transmission and distribution business operator. For example, as shown in FIG. 3, the supply and demand adjustment market bid processing device 100 includes an adjustment force requirement calculation unit 301 for calculating an adjustment force requirement in an area under its jurisdiction.

The supply and demand adjustment market bid necessity determination unit 206 calculates the transaction price predicted by the adjustment power transaction price prediction unit 204, the operating cost managed by the in-house adjusted power supply information management unit 205, and the adjustment power requirement calculation unit 301. Based on the required amount of adjustment power to be adjusted and the amount of adjustment power procured from the adjustment power supply of the supply and demand adjustment market, it is determined whether or not a bid is required for the supply and demand adjustment market. The supply and demand adjustment market bid necessity determination unit 206 calculates, for example, various actual values and predicted values (planned values) calculated by each processing unit 202 to 206 and recorded in the storage units 214 and 215, and the required adjustment power. Compare with the required amount of adjustment power (required amount of adjustment power) in your area calculated by Department 301, and procure from the supply and demand adjustment market 130 by the amount that the procurement cost of adjustment power is less than the operating cost of your own adjustment power supply. The bid amount (market procurement amount) is calculated with the above as a judgment condition. The required amount of adjustment force in the own area may be set by the operator via a screen or the like, in addition to being calculated by the adjustment force required amount calculation unit 301.

FIG. 4 is a diagram showing an example of a processing procedure for calculating a bid amount (market procurement amount) in the supply and demand adjustment market bid processing device 100.

First, the power demand forecasting unit 201 predicts the power demand in the time section (the time section) of the processing target (step S401).

Next, the supply capacity management unit 202 calculates the supply capacity of the time cross section (step S402).

Next, the grid operation information prediction unit 203 predicts the free capacity of the interconnection line in the time section (step S403).

Next, the adjustment power transaction price prediction unit 204 predicts the adjustment power transaction price in the time section (step S404).

Next, the supply / demand adjustment market bid necessity determination unit 206 has the adjustment power procurement cost (the price of the adjustment power transaction price in the time section plus fees, etc.) and the company's own adjustment power supply information management department 205. The operating cost of the regulated power supply is compared for each regulated power supply on the market (step S405). If the supply / demand adjustment market bid necessity determination unit 206 determines that the adjustment power procurement cost is lower than the operating cost of the in-house adjusted power supply, the processing is transferred to step S406 as the market procurement, and the adjustment power procurement cost is the in-house adjusted power supply. If it is determined that the operating cost is not less than the above, it is assumed that the product is not procured in the market, and the process is moved to step S408.

In step S406, the supply and demand adjustment market bid necessity determination unit 206 determines whether or not the adjustment power requirement of the own area calculated by the adjustment power requirement calculation unit 301 is satisfied by the market procurement amount. When the supply and demand adjustment market bid necessity determination unit 206 determines that the required amount of adjustment power in the own area can be satisfied by the market procurement amount, the process is transferred to step S407, and the required amount of adjustment power in the own area cannot be satisfied by the market procurement amount. If it is determined, the process from step S405 is repeated for another regulated power supply on the market.

In this way, the supply / demand adjustment market bid necessity determination unit 206 determines the transaction price and procurement cost of the adjustment power supply to be processed until the adjustment power requirement is satisfied in order from the adjustment power supply having the lowest adjustment power procurement cost in the supply / demand adjustment market. When the adjustment power adjustment cost including the above is compared with the operating cost and it is determined that the adjustment power adjustment cost is equal to or higher than the operating cost, it is determined that the adjustment power supply to be processed will not be bid on the supply and demand adjustment market. If it is determined that the adjustment power adjustment cost is less than the operating cost, it is determined to bid on the supply and demand adjustment market for the adjustment power supply to be processed.

In this embodiment, if the required adjustment power does not satisfy the procurement amount of adjustment power, it is determined that the required adjustment power is procured from the adjustment power source to be processed, and the required adjustment power does not satisfy the procurement amount of adjustment power. In this case, it is decided to procure the adjustment power procurement amount from the adjustment power supply to be processed, and the remaining adjustment power requirement (adjustment power requirement-the adjustment power procurement amount to be processed) is procured from another adjustment power supply on the market. However, it is not limited to this.

In step S407, the supply / demand adjustment market bid necessity determination unit 206 calculates the sum of the adjustment power procurement amount as the adjustment power market procurement amount (bid amount).

In step S408, the supply / demand adjustment market bid necessity determination unit 206 makes it impossible to procure the adjustment power in the market, and ends the process.

According to the above-mentioned processing, the general power transmission and distribution business operator can procure the market if it is possible to reduce the cost by procuring and operating the adjustment power over a wide area.

(3) Third Embodiment On the other hand, in the power generation / retail business operator, the electric power demand amount is predicted in advance, the supply amount is adjusted according to the prediction, and the electric power demand amount and the electric power supply amount are matched. It is necessary to achieve the same amount for 30 minutes at the same time. In order to minimize the gap (imbalance) between this power demand and power supply, it is required to accurately predict the power demand and to appropriately procure the required power demand. There is. In this regard, a technique for calculating an imbalance amount and supporting the elimination of the generated imbalance is disclosed (see JP-A-2017-182698).

Further, the technique described in Patent Document 2 is a technique for utilizing a transaction of electric power energy (kWh) in order to minimize imbalance, and an adjusting force (adjusting power source) for eliminating the generated imbalance. It is not intended for (ΔkW) transactions.

In this embodiment, an example of the case where the supply and demand adjustment market bid processing device 100 is applied to the supply and demand adjustment system 120 of a power generation / retailer will be described. For example, as shown in FIG. 5, the supply / demand adjustment market bid processing device 100 includes an energy transaction price forecasting unit 501, an adjusting power supplyable amount calculation unit 502, and an energy transaction record / forecast 511.

The energy transaction price forecasting unit 501 records the past transaction results of the Japan Electric Power Exchange 150 as actual values in the energy transaction results / forecast 511. In addition, the energy transaction price forecasting unit 501 predicts the future energy transaction price from the transaction actual value, the electric power demand forecast value, the supply capacity plan value of each company, etc., and the predicted energy transaction price is the energy transaction actual / forecast 511. Record in.

The adjusting power supplyable amount calculation unit 502 calculates the power selling merit in the energy transaction excluding the operating cost and the cost related to the power selling from the transaction price predicted in the energy trading market. The adjusting power supplyable amount calculation unit 502 uses, for example, the predicted price of the energy transaction calculated by the energy transaction price prediction unit 501 as input information, and has the merit of selling electricity in the energy transaction (profit, for example, income (for sale). Price) -Cost (operating cost, fee, etc.)) is calculated.

The supply / demand adjustment market bid necessity determination unit 206 bids on the supply / demand adjustment market based on the transaction price predicted to be traded in the energy transaction market and the transaction price predicted by the adjustment power transaction price prediction unit 204. Judge the necessity. The supply / demand adjustment market bid necessity determination unit 206 is, for example, in the adjustment power transaction from various actual values and predicted values (planned values) calculated by each processing unit 202 to 206 and recorded in the storage units 212 to 216. When the merit of selling power in the energy transaction is lower than the merit of selling power in the energy transaction, compared with the merit of selling power in the energy transaction calculated by the power selling merit of , The bid amount (market power sale amount) and the bid price are calculated on the condition that a sell bid is made to the supply / demand adjustment market. Here, the calculation conditions for the merit of selling electricity in each market may be configured to be set on the screen or the like by the operator.

FIG. 6 is a diagram showing an example of a processing procedure for calculating a bid amount (market power sale amount) in the supply and demand adjustment market bid processing device 100.

First, the power demand forecasting unit 201 predicts the power demand in the time section (step S601).

Next, the supply capacity management unit 202 calculates the supply capacity of the time cross section (step S602).

Next, the system operation information prediction unit 203 predicts the free capacity of the interconnection line in the time section (step S603).

Next, the adjustment power transaction price prediction unit 204 predicts the adjustment power transaction price in the time section (step S604).

Next, the supply and demand adjustment market bid necessity determination unit 206 calculates the merit of selling electricity in the adjustment power transaction based on the adjustment power transaction price (step S606).

The supply and demand adjustment market bid necessity determination unit 206 compares the merit of selling power in the adjustment power transaction with the merit of selling power in the energy transaction (step S606). If the supply / demand adjustment market bid necessity determination unit 206 determines that the power selling merit in the adjustment power transaction exceeds the power selling merit in the energy transaction, the process is transferred to step S607 as a selling bid to the supply / demand adjustment market. If it is determined that the merit of selling electricity in the adjustment power transaction does not exceed the merit of selling electricity in the energy transaction, it is assumed that the selling bid is not made in the supply and demand adjustment market, and the process is moved to step S608.

In step S607, the supply and demand adjustment market bid necessity determination unit 206 calculates (determines) the bid amount (market power sale amount) and the bid price for the supply and demand adjustment market 130.

In step S608, the supply and demand adjustment market bid necessity determination unit 206 determines that the market power of the adjustment power cannot be sold, and ends the process.

In this way, the supply / demand adjustment market bid necessity determination unit 206 is based on the merit of selling electricity in energy transactions calculated by the adjustment power supplyable amount calculation unit 502 and the transaction price predicted by the adjustment power transaction price prediction unit 204. Comparing the merit of selling power in the adjustment power transaction excluding the operating cost and the cost related to the power sale, and determining that the merit of selling power in the energy transaction is smaller than the merit of selling power in the adjustment power transaction, supply and demand. Judge to bid on the adjusted market.

According to the above-mentioned processing, the power generation / retailer can trade in the market where the adjusting power (adjusted power source) of the power generation / retailer can be sold at a higher price.
