Z1). ~ Zn) to host: management computer 21) makes it possible to divert existing Ethernet infrastructure and solves cost and security problems due to global IP required for downstream communications (from host to local) is doing. In this regard, in the past, the method of collecting individual data from customers (A1 to An,... Z1 to Zn) is largely different from the mainstream method using a telephone line or a Dupa network.

  According to the wide area power data comprehensive management system 1 according to the present embodiment described above, the company (A to Z), the customer (A1 to An,... Z1 to Zn), the supply sources α, β, γ, power management. Each of the institutional data centers 5 can enjoy the following advantages.

  In the company (A to Z), the contract capacity (= basic charge) has been determined based on the maximum demand in the contract unit (1 contract / 1 establishment) of the power contract with the supply sources α, β, γ. As a result, the basic fee when a plurality of customers (A1 to An,... Z1 to Zn) are owned is the sum of the individual basic fees, whereas the customers (A1 to An,...・ Contracting contracts based on the maximum value of time series aggregation of multiple customers (A1 to An, ... Z1 to Zn) by real-time aggregation of power data of Z1 to Zn) (eg; aggregation of A1 to An) As a result, the economic effect of reducing the contract capacity (= basic charge) due to the difference between the total individual maximum power and the maximum power after consolidation can be expected.

  Also, by analyzing the individual power data of customers (A1 to An,..., Z1 to Zn), it becomes possible to grasp the usage status of power, and through the extraction of power waste factors, planning, execution and verification of measures Efforts for power saving are possible.

  The data center 5 of the power management organization makes the company (A to Z) a combination of different industries with different power usage patterns, so that the difference between the maximum power total for each company (A to Z) and the time series total power maximum value is different. Can be increased by the combination of different industries, and profit is generated for the difference between the contracted capacity under the maximum power conditions with the suppliers α, β, and γ and the total maximum power by company (A to Z). .

  In addition, since the amount of power procured for the company (A to Z) is very large, from the viewpoint of the suppliers α, β and γ, the power consumption is huge and the usage is flat. From becoming a house,

  It is possible to procure electricity from suppliers α, β, γ at a low price with a strong bargaining power due to this scale merit, and companies (A to Z), customers (A1 to An, ... Z1 to Zn), and power management organizations The profits of the data centers 5 can be obtained.

  The supply sources α, β, and γ can supply power to small customers (A1 to An,..., Z1 to Zn) that have not been sold because of the power consumption scale. The increase in power supply (= sales increase) can be expected.

  Further, the supplier of the measurement and communication terminal 3 defines its own customer as a power management organization (aggregator) in addition to the revenue from the supply of the measurement and communication terminal 3 to the customers (A1 to An,... Z1 to Zn). You can expect profits through the brokerage business introduced in, and business opportunities such as measurement and communication terminal 3 maintenance.

  Thus, according to the wide area power data comprehensive management system 1 according to the present embodiment, it is possible to contribute to the expansion of the scope of the liberalized market by supporting the same amount countermeasures such as the power supply sources β and γ. , Enabling small-scale customers to participate in the liberalization market that could not benefit from the liberalization of electricity, and reducing the energy cost of energy and grasping the current situation of energy consumption through time-series management of power data It can greatly contribute to comprehensive power saving activities.
