That is, the acquired vacant space information output unit 36 is configured such that the power generation company that owns or operates each of the power generation facilities 1 to 4 is the “matching transaction business operator (to be described later) that mediates the buying and selling of the interconnected vacant space,” or Information on the interconnected vacant frames acquired from “another power generation company” via the “linked vacant exchanges” is acquired from the interconnected vacant frame acquisition unit 35 (described later).

  As described above, the total generated power acquisition unit 31 calculates the calculated total generated power at a predetermined time interval (for example, a time interval such as 5 minutes or 10 minutes), that is, every predetermined time zone. Output to. When the determination unit 32 receives the total generated power from the total generated power acquisition unit 31, the determination unit 32 accesses the total interconnection supply capacity frame acquisition recording unit 33 to obtain the total interconnection supply capacity frame acquisition recording unit 33. To obtain the total interconnection supply capacity frame at that time (time zone) recorded in. And the said determination part 32 is the same time slot | zone (predetermined) from the total generated power of the said time slot | zone (predetermined time interval) from the said total generated electric power acquisition part 31 and the said total interconnection supply capacity frame acquisition recording part 33. Time interval) and the total interconnection supply capacity frame, and if the total generated power exceeds the total interconnection supply capacity frame in the time zone (predetermined time interval) (or the time zone (predetermined time) (When it is predicted that there is a high possibility of exceeding in the interval)) and the generated power amount exceeding that (or the generated power value predicted to be high in the time zone (predetermined time interval)), It outputs to the interconnection supply power adjustment unit 34.

  The interconnection supply power adjustment unit 34 determines that the total generated power exceeds the total interconnection supply capacity frame in the time period (predetermined time interval) from the determination unit 32 (or the time period (predetermined time) (The interval) is highly likely) and the amount of generated power exceeding (or the amount of power generated that is predicted to be highly likely to be exceeded in the time period (predetermined time interval)), the total generated power is It adjusts so that all or one part of each generated electric power from each said power generation equipment 1-4 may be suppressed so that the said total interconnection supply capacity frame may not be exceeded.

  First, the grid supply power adjustment unit 34 transmits a control signal to the charge / discharge control unit 22 so that a part of the generated power from each of the power generation facilities 1 to 4 is stored in the storage battery 23. Thus, each power generation amount supplied from the power generation facilities 1 to 4 to the power receiving / transformation facility 16 is suppressed. In this way, when the excess generated power is stored in the storage battery 23, the generated power of each of the power generation facilities 1 to 4 is suppressed (for example, peak cut by a power conditioner, which will be described later, steam power generation in a geothermal power generation facility) In principle, there is no need to reduce the amount of supply to the turbine or the amount of fuel supplied in the biomass power generation facility.

  Further, for example, the interconnection supply power adjustment unit 34 transmits a control signal to the power conditioners 5 and 6, and each of the power conditioners 5 and 6 receives the wind power generation equipment 1 or the solar power generation equipment 2. The maximum value of the generated power is cut (for example, the peak is cut by a technique such as surge control), thereby suppressing the amount of generated power from the wind power generation facility 1 and the solar power generation facility 2. In addition, the interconnected power supply adjustment unit 34 transmits a control signal to the steam amount adjustment unit 3a, for example, to supply the steam generation unit 3a to rotate the power generation turbine in the geothermal power generation facility 3. The amount of generated steam is suppressed, thereby suppressing and adjusting the amount of generated power from the geothermal power generation facility 3. In addition, the interconnection supply power adjustment unit 34 transmits a control signal to the fuel supply amount adjustment unit 4a, for example, and the wood chip to the combustion unit in the biomass power generation facility 4 is transmitted by the fuel supply amount adjustment unit 4a. Thus, the amount of fuel supplied from the biomass power generation facility 4 is suppressed and adjusted.

Is a matching unit that matches each other (and establishes a transaction based on a limit or a course).

  Next, the operation of the matching system (hybrid system trading system) 44 will be described with reference to FIG. The vacant frame output unit 48 transmits data necessary for power generation such as transmission output data of existing renewable energy (365 days, 24 hours), solar radiation amount for solar light, wind condition data for wind power, and biomass supply amount for biomass ( Data recorded in the operation status related database 45) and each interconnection supply capacity frame permitted for each power generation facility owned by a large number of power generation companies participating in the transaction (the interconnection supply capacity frame) Based on the data recorded in the database 46), etc., the interconnected vacant frame (system vacant frame) during normal operation is calculated and output for each fixed time period. In other words, the vacant frame output unit 48 indicates that “the time period during which the operator does not plan to use” in the interconnection supply capacity frame permitted for each power generation facility owned or operated by a number of power generation operators. The empty frame corresponding to is obtained and output.

  The matching unit 49 uses the solar radiation amount of existing locations of renewable energy, wind condition prediction data, biomass existence amount, water system data (each prefecture), and geothermal potential data as input data for each interconnection supply capacity. Simulates the optimal combination of open and closed sell orders and buy orders. Then, the matching unit 49 provides the simulation result to each power generation company that owns each renewable energy power generation facility such as solar power, wind power, biomass, geothermal power, hydropower, etc. Encourage consideration of the purchase and sale of interconnected vacancies in the capacity frame. Data on the series of operations described above is disclosed on the Internet homepage, and a matching transaction is realized especially for a new renewable energy power generation company.

In addition, (2) for existing renewable energy power generation companies, it can be expected to improve the facility utilization rate of the power generation facilities they own and increase profits (increased yield) by reselling linked vacancies. In addition, (3) new renewable energy power generation companies are expected to have the effects of reducing grid burden, shortening the grid connection process, and reducing the amount of investment by purchasing interconnection vacancies.
