Smart microgrid management and control system and smart power management method

A smart microgrid control system and a smart power management method, the smart microgrid control system comprises: a controller, a plurality of loop monitoring auxiliary machines, a server, an electric meter, and a battery. It has functions such as power safety, power overload warning, and power abnormal warning. At the same time, it has the function of cloud service, which can transmit the operation status data of various energy-consuming facilities to the cloud server. Users can remotely control the operation and use of various energy-consuming facilities through the remote control of the Internet device to achieve intelligent management effect.

The traditional switchboard is usually a configuration device that performs circuit control of circuit switches of a single type of equipment. It concentrates the switches of the power circuit in one box to make a branch, and forms a short-circuit protection function when the power is overloaded. Because it is mostly equipped with the same function, it can only switch the line control of the same type of electrical appliances or energy-consuming facilities, and there is no further extension of other technologies and functions other than power. Functionally weak.

However, the fuseless switch used in the conventional switchboard does not collect power consumption information, so it is usually tripped in a physical thermal sense, and the rated current is classified, and the flow must be greater than the rated current. The greater the overload current, the shorter the trip speed is. For abnormal power consumption less than the rated current, there is no function. For a current equal to or slightly larger than the rated current, the tripping time is too long, so strictly speaking The overload protection capability is insufficient, and the short-circuit protection capability may be acceptable. Because there is no self-function diagnosis capability, it is impossible to distinguish between good and bad, and safety is really worrying. Since the switchboard cannot collect power consumption information, the characteristics of the end electrical equipment are often used to classify the power circuit, such as air conditioning, lighting, socket power circuit or specific electrical circuit, etc., and the configuration rule is used as future power consumption. The method of forecasting the total amount is used as the design basis for loop overload protection. Therefore, there will be repeated wiring in the same area, which wastes the cost of construction and limited natural resources.

In addition, the traditional switchboard has no built-in computing and monitoring capabilities, so it is impossible to avoid the waste of use caused by insufficient professional knowledge and the use efficiency caused by uncontrollable environmental dynamics. It is neither energy efficient nor can it be reduced. carbon. At the same time, there is no external communication capability in the traditional switchboard. Apart from the inability to solve the current situation of "no worries and unevenness", it is impossible to develop innovative applications for various types of connected electricity.

In addition, the traditional power distribution board only has the power branch transmission function, and cannot provide the management capability of the dynamic route exchange. Therefore, there is only a single power source, and the power conversion capability is not automatically switched to the backup power source capability, and the lowest cost route cannot be selected immediately. Reduce the cost of electricity.

The traditional electric meter is only designed for the measurement of the power supply. Its function is usually only used to calculate the electricity bill by the power supply company. The function is simpler and only limited to electricity measurement. It does not have information. Communication functions, and there is no technology development for developing related applications to connect external systems for advanced intelligent management.

The general grid architecture on the market is a power supply network connecting the supply end and the customer end. It consists of a power generation system, a transmission system and a power distribution system. Its function is mainly as the transmission and distribution of power, and does not include other energy-related hard Physical equipment, or intelligent power management equipment. Because it is only used as a network connection for power supply, transmission and distribution, its internal structure only deals with functions related to transmitting power, and cannot perform more subtle performance in terms of power consumption, and cannot be used in other energy consumption effects. Do play.

The power overload management (23) can provide users with self-definition thresholds for different areas according to different conditions of people, things, places, objects, time, etc., and the system has self-diagnosis and real-time power monitoring functions. In the event of an overload protection device failure or power overload, the system will immediately notify the manager via SMS or email, and if necessary, cut off the loop power to avoid disasters. For example, the home outlet circuit is used to indicate that the overload threshold is 20 amps during the day when the person is at home. When the person goes out or sleeps at night, the overload threshold will be automatically set to 1 amp depending on the time period or event. Electricity abnormality management (25) mainly monitors the electric ray and numerical data of various energy-consuming equipment. The computer installs various electric energy data (normally operated equipment) through the pre-setup and learning functions. The electro-pattern database can instantly determine which energy-consuming equipment is being monitored and whether the energy-consuming equipment is operating normally through the comparison between the electric patterns generated by the actual use of the energy-consuming equipment and the electric patterns in the database.

For example, the computer pre-stores the embossed data during normal operation of the device, called the database embossed data (62), and compares it with the actual embossing (64) of the device transmitted by the server (16), ie It can instantly know that the equipment is in normal or abnormal operating state. If it is in an abnormal state, it can immediately warn the user, allowing the user to carry out subsequent inspections, repairs, etc., to achieve monitoring and management of the equipment. . The computer collects the current according to the current used by the electrical equipment and the values recorded by the relevant environmental sensors, including amps, °C, percentage, etc., and can compare the operation of the equipment according to the long-term historical use data, once the energy-consuming equipment is used. Differences with historical data, the system can immediately notify the manager to confirm. The energy-consuming device monitors the electric-gravity comparison as if the ECG of the energy-consuming device is known. Once any part of the device is abnormal, the system can immediately notify the manager to perform the maintenance to maintain the operation of the energy-consuming device. quality. Taking an energy-consuming electrical equipment as an example, it is assumed that the long-term current monitoring data shows that its normal operating current is 3 amps. If the current reading value is suddenly detected to be 6 amps, the system will be regarded as an abnormal condition and an alarm will be issued to notify the manager to confirm. . In addition, the system can also know the equipment to be monitored according to the electric pattern comparison. The user can define the equipment that the space can be allowed to use according to the front surface according to the environmental conditions, or set the equipment that is not allowed to be used in a negative manner. To improve the safety of environmental electricity. For example, in a restaurant room, the manager can negatively set a prohibition to use some of the more dangerous high-load devices for the safety of the tenant. Once the system detects that the device is used, it will immediately cut off the circuit and notify the manager to confirm.

As mentioned above, the power efficiency management (22) includes two parts: usage management (24) and demand management (26). The usage management (24) is to transmit the energy consumption equipment connected in the building to the cloud server after establishing the lowest cost route. After the user knows the power consumption information of the equipment through the Internet access device, According to the dynamic rate of the power company, according to the time limit, the individual power thresholds of peaks and peaks can be set, or the contract capacity can be signed with the power company to form the most suitable energy-saving plan for electricity consumption, thereby reducing the cost of electricity consumption. In terms of demand management (26), the user can refer to the power company's power supply price ratio (the ratio of power quality to value), and store and trade the power in time to achieve the best performance and best quality of power utilization. Get the best economic benefits.

Therefore, the smart micro-grid control system and the smart power management method of the present invention can issue a warning message to a designated user when the power consumption of the energy-consuming device is overloaded or abnormal, so that the user can immediately grasp any power safety. The abnormal condition includes functions such as power safety, power overload warning, and power failure warning.
