Description

本発明は、余剰電力の管理に係り、特に使用発電設備を自然エネルギー利用全般とした、企業のＣＯ２排出削減につながる余剰電力の売買契約を有する余剰電力管理システムに関する。 The present invention relates to surplus power management, and more particularly, to a surplus power management system having a contract for surplus power that leads to a reduction in CO 2 emissions of a company, in which a power generation facility used in general uses natural energy.

ＣＯ２排出削減は、地球温暖化防止策として必須であり、社会的にも要求が高い。太陽光発電や風力発電、燃料電池等は、ＣＯ２を排出しない発電システムとして需要が伸びてきており、家庭用自然エネルギー発電装置としても普及率が上がる傾向にある。太陽光発電などは、電気事業者が余剰電力を買い取るシステムも整備されてきた。 Reduction of CO 2 emissions is indispensable as a measure for preventing global warming and is highly demanded by society. Demand for solar power generation, wind power generation, fuel cells, and the like is growing as a power generation system that does not emit CO 2, and there is a tendency for the penetration rate to increase as a home-use natural energy power generation apparatus. For solar power generation, etc., a system has also been established for electric utilities to purchase surplus power.

製造業等（製造業に限らない）電力消費量の大きい需要家、企業は、何らかの発電装置を保有していないとき、電力の需給は発電事業者（電力会社）や売電事業者等の電気事業者からである。企業が電力の需給に関してＣＯ２削減に貢献しようとする場合、やはり、ＣＯ２を排出しない太陽光発電や風力発電、燃料電池等の自然エネルギー発電装置の設備が必要である。 When a consumer or a company with a large amount of power consumption (not limited to the manufacturing industry) or a company does not have any power generators, the supply and demand of electricity is generated by electricity from a power generation company (electric power company) or a power sales company. From the business. When a company intends to contribute to CO 2 reduction with respect to the supply and demand of electric power, it is necessary to provide facilities for natural energy power generation devices such as solar power generation, wind power generation, and fuel cells that do not emit CO 2 .

従来、電力消費量の小さい需要家から、製造業者等電力消費量の大きい需要家までの複数の電力需要家をグループ化し、統合的に管理するシステムが開示されている（例えば、特許文献１参照）。これらのグループ内には、上記したような家庭用自然エネルギー発電装置やディーゼル発電装置、マイクロガスタービン発電装置等、小規模分散型電源を保有している需要家が含まれている。そこで、グループ間の電力供給をグループ内全体で協調して調整するため、電力供給制御装置を設ける。これにより、需給調整の際に、余剰電力を電気事業者に供給する一方、不足電力を各電力需要家の需要に応じて上記電気事業者から配分してもらうようにする。これにより、グループ内の分散型電源による余剰電力をグループ内の他の需要家で有効に活用することができる。
特開２００２−１０４９９号公報（３頁、図１） 2. Description of the Related Art Conventionally, a system that groups and manages a plurality of power consumers ranging from consumers with low power consumption to consumers with high power consumption such as manufacturers has been disclosed (for example, see Patent Document 1). ). These groups include customers who have small-scale distributed power sources such as the above-mentioned home-use natural energy power generation devices, diesel power generation devices, and micro gas turbine power generation devices. Therefore, a power supply control device is provided in order to coordinate power supply between groups in a coordinated manner throughout the group. Thereby, at the time of supply-demand adjustment, while supplying surplus electric power to an electric power company, it is made to allocate shortage electric power from the said electric power company according to the demand of each electric power consumer. Thereby, the surplus electric power by the distributed power supply in the group can be effectively utilized by other consumers in the group.

以上説明したように本発明によれば、企業として、使うことのできる余剰電力は、自然エネルギー利用全般とした自然エネルギー発電が担う。企業として、例えば自社工場で使用する電力のうち、売却量分のＣＯ２削減を実施したと算出することができる。使用発電設備は、家庭向けあるいは小中規模で、設置しやすい分散型発電装置となり、分散型発電装置を利用した総合大容量の発電システムが構築できる。企業は、従業員との契約及び電気事業者との契約により、余剰電力を一括して売買する。これにより、相当量のＣＯ２削減に寄与する。また、従業員の家庭においても、エネルギー消費に関るＣＯ２発生がなくなり、地域社会への自然エネルギー発電の普及促進が図れる。企業と地域の環境対策としても有効である。この結果、一企業が自然エネルギー発電装置の設備を効率良く配備または保有することができ、ＣＯ２換算量等の把握等、ＣＯ２削減の貢献度合いが確認できる余剰電力管理システムを提供することができる。 As described above, according to the present invention, surplus electric power that can be used as a company is borne by natural energy power generation that uses natural energy in general. As a company, for example, it can be calculated that CO 2 reduction for the sales amount of electric power used in its own factory has been carried out. The power generation equipment used is a home-use or small / medium scale distributed power generator that is easy to install, and an integrated large-capacity power generation system using the distributed power generator can be constructed. The enterprise buys and sells surplus power in a lump sum based on a contract with an employee and a contract with an electric power company. This contributes to a considerable amount of CO 2 reduction. In addition, CO 2 generation related to energy consumption is eliminated in the employee's home, and the spread of renewable energy power generation to the local community can be promoted. It is also effective as an environmental measure for companies and regions. As a result, it is possible to provide a surplus power management system in which one company can efficiently deploy or own the facilities of a natural energy power generation apparatus and can confirm the degree of contribution of CO 2 reduction, such as grasping the CO 2 equivalent amount. it can.
