Power monitoring system in zero energy building {POWER MONITORING SYSTEM IN ZERO ENERGY BUILDING}

The present invention relates to a power monitoring system of a building, and in particular, a zero-energy building that acquires energy use information for each electrical load of the building and information on the amount of energy produced by new and renewable energy, and monitors it in real time and manages it in an integrated manner. It relates to a power monitoring system in the.

In general, in the power system system, the control system manages the storage of idle power for power stabilization and power quality stabilization. As an example, an uninterruptible power supply (UPS) device provides stable power of good quality by overcoming an unexpected power failure that may occur in a commercial power source.

In addition, the energy storage system (ESS) stores spare power in advance and supplies stable power with the saved spare power in case of an emergency such as a power outage. Uninterruptible power supply (UPS) and energy storage (ESS) are being introduced to ensure the reliability of power supply in various fields such as finance, broadcasting, and industry where stable supply of power is important.

In recent years, issues of energy resource depletion due to fossil fuels, issues of environmental pollution, and economics of energy use have emerged as important, effectively overcoming the mismatch between power consumption and power production, and wasting due to excessive power supply. And in order to solve the overload phenomenon caused by a shortage of power supply, the concept of a smart grid system in which the amount of power supply is flexibly adjusted in connection with various information and communication infrastructures has been actively studied.

The smart grid system has a plurality of constituent facilities corresponding to the main body of electricity generation or consumption as members. Among the above components on the smart grid, distributed power generation facilities with power generation facilities (e.g., facilities with self-generation facilities such as solar heat, wind, etc.) store the generated power when the power consumption is low, but when the power consumption is high, the stored power It will have an infrastructure structure that allows it to be supplied to consumers with production power.

That is, the smart grid system is a form of a next-generation power network using information communication technology in a power network. The smart grid system is a form of overlaying a network measurement system including smart meter information and an existing power grid including consumption self-power usage information, and provides two-way digital communication between a supplier and a consumer. By allowing the power to be controlled through energy saving, reliability and transparency are increased.

Such a smart grid system is a word from the US Economic Week Business 2.0 introducing eight technologies that will save humanity from extreme weather and environmental pollution caused by global warming, and the smart grid system was selected as one of the three technologies.

The industrialization of mankind has made it difficult to secure energy due to the increase in energy consumption, and caused excessive emission of CO ₂ , the main culprit of global warming. The smart grid system is an energy-saving power grid that can solve such a crisis of securing energy and the critical problem of global warming.

The smart grid system reduces energy waste by improving energy efficiency, reduces dependence on overseas energy through activation of distributed power generation based on new and renewable energy, and reduces the use of fossil fuels in existing power generation facilities. Can be called.

In addition, each country that promotes the smart grid system is making efforts to create a demonstration complex. Through the creation of a smart grid demonstration complex, it is expected to test the energy, economic, and industrial success of the smart grid industry and revitalize local industries.

In the case of Korea, by establishing a plan to implement a smart grid at a national level, by 2030, energy savings were 2%, national greenhouse gas emissions were reduced by 41 million tons (7% of 2006 emissions), and fossil fuels were imported in terms of trade balance. It is expected to save $10 billion in energy imports through the reduction. In addition, through the creation of a demonstration complex in the Jeju region, it is expected to revitalize the Jeju region's economy, relieve youth unemployment, and enter into overseas markets, resulting in economic and industrial positive effects.

The smart grid system is provided by a device that senses, measures, and controls information about the grid status in two-way communication to system users, operators and automatic devices for the electricity production, transmission, distribution, and consumption portion of the power grid. For the provision of such smart grid technology, the range of technology is very broad as the complexity of technology such as transmission network, distributed automation, demand response (DR), advanced metering infrastructure (AMI), and electric vehicles, and its importance is also high. .

Accordingly, smart grid technology is being studied in various ways, and its market size is expected to continue to rise, and standardization is being actively conducted in various countries and international standardization organizations for smart grid-related standardization.

Technologies for implementing the smart grid system may be largely divided into a distributed power field, a power grid management field, and a user power management field. And, technologies in the field of distributed power include Distributed Resource technology and Energy Storage Integration technology, and technologies in the field of power grid management include Real-time Monitoring technology and transmission and distribution automation. There are (Transmission/Distribution Automation) technology, demand response (DR) technology, and communication network technology, and the technologies in the user power management field include Smart Meter, Smart Building, and smart home appliances. (Smart Appliance), Consumer Voltage Regulation technology.

In such a smart grid system, distributed power generation facilities are introducing uninterruptible power supply (UPS) and energy storage (ESS) to stabilize power. Meanwhile, the smart meter is an advanced metering infrastructure (AMI), and performs power metering to measure the power consumption of power consumers such as home/apartment/building that consumes power, and related power Transfer the information to a separate operation center.

However, the existing smart meter, that is, the advanced metering infrastructure (AMI), is buried and installed in a specific place provided in, for example, home/apartment/building, and it is difficult for individual managers to directly check the power consumption of power consumers in real time. There is this.

On the other hand, the power supplied to the installation location where the existing smart meter is installed is distributed through a distribution board or the like to supply power to a plurality of loads. For example, when the installation location is a large building, the total power supplied to the large building is distributed to each floor (ie, a plurality of loads), so that each power is supplied.

In this case, the conventional smart meter can only calculate the power amount of the entire installation location (i.e., a large building in the above example), and the current flowing through each load (i.e., each floor in the above example) and each There is a problem in that the amount of power consumed by each load cannot be calculated because the amount of power used by the load of is not detected.
