Description

IoT-based power reduction system The present invention relates to an IoT-based power saving system, and more specifically, to an IoT-based power saving system capable of preventing unnecessary power consumption and reducing power demand by using a smart circuit breaker to cut off standby power and leakage current. The electricity demand management business is a new concept in the power market known as "negative generation" (also known as the "negawatt market"). It involves operators generating revenue through settlement payments by trading the amount of electricity they reduce in consumption against power plants in the power market. In other words, it is a system where various institutions or general consumers enter into contracts with demand management operators to reduce their existing electricity usage and sell the reduced amount to Korea Electric Power Corporation (KEPCO). Under this system, institutions and consumers—such as buildings, factories, and large supermarkets—contract with the demand management operator to use less electricity than their usual consumption; the operator then aggregates the saved electricity and sells it to KEPCO, sharing the profits. According to this system, operators determine the price at which they will sell the saved electricity and place bids between 5:00 AM and 10:00 AM. Transactions take place through the Demand Response Resource Power Trading System, a computerized trading network of the Korea Power Exchange. A bid is awarded if the unit price offered by the demand management operator is lower than the marginal generation cost of the power generation company. Additionally, a transaction is concluded only if the monthly reference price is lower than the generation cost of the power plant. It was initiated with the aim of conserving electricity in facilities such as factories and buildings and reselling it, rather than generating new electricity. In other words, instead of increasing power generation to meet high consumption, the approach involves lowering consumption itself to match the amount of electricity generated. This is attracting attention as a new energy business combined with Information and Communication Technology (ICT) and has already become commonplace in developed countries such as the United States, the United Kingdom, and Germany. Accordingly, a power system has been disclosed that enables efficient energy management by integrating a safety cutoff device, a standby power cutoff device, a heating and cooling controller, and a power monitoring device, and can increase safety against electronic overload, leakage current, short circuit, and system overheating. However, in the case of standby power cutoff, since the method involves measuring input and output power and shutting off the power switch only when the measured power value is identical to a preset standby power cutoff value within the margin of error, there is a problem in that power will inevitably continue to be consumed if the measured power value is not identical to the preset value within the margin of error; this ultimately means that it cannot serve as a fundamental solution to cut off standby power. Furthermore, household power strips used to cut off standby power mainly consist of products that must be connected to individual outlets linked to mobile carrier paid services, and there is the inconvenience of users having to manage them by cutting off standby power through ON/OFF time setting modes. In addition, there is a problem in that existing standby power products are limited to standby power cutoff technology at the lower level connected to outlets, etc., and standalone devices, multi-tap devices, and power control devices linked to PCs are used to cut off power. However, standalone power control devices are smart outlets and plugs that are plugged into each outlet, and they can only measure and control the corresponding outlet partially, and there is the inconvenience of having to attach them to each outlet. Furthermore, multi-tap type devices can only control plugs connected to the multi-tap and do not control other individual plugs; they are primarily used for communication devices from mobile carriers, whereas power control devices linked to PCs are suitable for building high-cost investment smart factories that manage power via PCs in medium to large-sized factories requiring specialized electrical management personnel. In addition, power cutoff and leakage prevention may be necessary not only to reduce electricity consumption but also in natural disaster situations, including earthquakes. Recently, natural disasters have become more frequent globally, and among them, Korea is proving to be no safe zone from earthquakes, as earthquakes of magnitude 4 or higher are occurring one after another at sea or inland. Accordingly, although power distribution panels capable of cutting off power in the event of an earthquake are provided, there is a problem where power is supplied even when
