Description

  Embodiments of the present invention relate to an energy management system (hereinafter referred to as EMS) that manages energy supply and demand in a smart community or the like.

  In general, a smart community is a society in which two-way information communication is possible between an energy supplier and a customer. For this reason, smart communities use smart meters to collect data on supply and demand results and equipment conditions, monitor supply and demand, forecast equipment, detect equipment abnormalities, generate control commands for equipment, and plan and maintain equipment operations. I have a plan.

  In such a smart community, EMS that manages energy supply and demand is indispensable. The following technologies have been proposed for EMS. For example, technologies that allow energy companies and users to collaborate to formulate control plans for electrical equipment, technologies that formulate power generation plans based on demand forecasts considering periodic inspection plans, and further reduce environmental impact in the room Techniques for estimating measures for each user and calculating the environmental load reduction effect for each user have been proposed.

Registration No. 4864809 JP 2010-114968 A JP 2012-44732 A

  With regard to EMS adopted in the smart community, it is expected to develop a technology for improving productivity as a whole society by making use of a two-way communication environment between energy suppliers and customers in the smart community. The improvement of productivity as a whole is to satisfy the demands of both energy suppliers and customers. For example, a request for EMS from the energy supplier side includes carrying out energy management including maintenance and management of facilities, and at the same time, fostering maintenance personnel.

  However, in conventional EMS, energy management and maintenance staff skill management are not linked to each other on the system. For this reason, it is difficult to create an operation plan and a maintenance plan that take into account the skills of workers. In addition, the conventional EMS has not quantified the skill improvement effect of maintenance personnel through maintenance results.

  By the way, while the energy supplier side is limited to business types such as an electric power company, a power transmission company, and a power generation company, the business types of consumers are diverse. In other words, the type of product produced by the consumer, the labor form, location, skill, and production capacity of the consumer vary depending on the consumer, and production activities differ accordingly. Therefore, the demand form of energy differs for each consumer.

  For example, when the consumer is a farmer, the growth timing of the agricultural product is different for each agricultural product, so the difficulty level of demand adjustment must be changed according to the growth timing. If there is a shiitake farmer (referred to as shiitake farmer A) among the consumers, shiitake farmer A can easily adjust the demand if the shiitake farming season is slow.

  However, since Shiitake farmer A gives priority to shipping, Shiitake Farmer A has difficulty in adjusting demand. In this situation, if there is a farmer who produces agricultural products with different growth timing from Shiitake in the same smart community, for example, a tangerine farmer B, between this tangerine farmer B and Shiitake farmer A, It is desirable to maintain both productivity while suppressing energy by not overlapping the time of energy increase.

  In view of these cases, the demand for EMS from the customer side is to increase productivity by increasing production volume and improving production quality while suppressing increase in energy consumption as a whole society. It is in. In other words, during energy management by EMS, the effects of season, weather, temperature, and time on quality and productivity are analyzed for each product, and the time of energy increase is considered in consideration of the characteristics of each combination of different products. It is demanded not to repeat.

  However, the conventional EMS does not have information for increasing the productivity of each consumer. For this reason, optimum energy management cannot be performed while utilizing the characteristics of each consumer. In addition, it is difficult for consumers to understand how much productivity has been improved by energy management. Accordingly, there is a demand for quantifying the effects obtained by consumers such as productivity improvement.

  An embodiment of the present invention solves the above-described problem, and has maintenance staff skill information to improve the quality of equipment maintenance and management to improve the equipment operation rate and to train maintenance personnel. In addition, by having information to enhance the quality and productivity of each product of the consumer, the productivity of each product is increased without increasing the overall power consumption by utilizing the characteristics of each product, The purpose is to provide an energy management system capable of quantifying customer effects and contributing to productivity improvement as a whole society.

In order to achieve the above object, an energy management system according to an embodiment of the present invention includes the following components (a) to (d).
(A) An operation plan drafting unit that drafts an operation plan for equipment.
(B) A maintenance staff information database storing at least maintenance staff skill information as maintenance staff information relating to maintenance staff registered in advance.
(C) A maintenance staff-specific instruction creation unit that creates instructions regarding predetermined work for each maintenance staff based on the maintenance staff information and the operation plan.
(D) An effect calculation unit that calculates at least one of the skill improvement level of the maintenance staff and the performance improvement level of the facility as an effect by performing the work in accordance with the instructions.

An energy management system having the following components (e) to (h) is also one embodiment of the present invention.
(E) An operation plan drafting unit that formulates an operation plan for equipment based on product influence information that affects products produced by consumers.
(F) A customer information database that stores customer information related to customers registered in advance.
