The key path of distributed power generation Suger Baby network The layer control of intelligent micro-network

The micro-network has two important development goals. First, connect the micro-network with the public major power network; second, connect multiple neighboring micro-networks to form micro-network groups (microgridclusters). Therefore, future power networks will include primary power, a primary motor, power electronic converter, DS device and local DL, and microphone network is just one of them. Microphone can be operated independently while logging in or connected to the major network. It is an important feature of micronetwork to perform seizureless switching between concurrent and off-network. Energy adjustment can be achieved between multiple micronets through the contact line between micronets to achieve the actual power equalization of each micronet at the same time. The mutual support between this micro-network plays a role in the increase and increase of each other, reducing the energy received by the micro-network from the public network, and further reducing the long-distance transmission consumption that is not required. In addition, the micronet is a brand new low-voltage distribution network. The generator sets not only contain small generators, but also small original machines, such as photovoltaic battery components, small wind generators, biofuel batteries, etc. These generators all require AC/AC or DC/AC converters as interface circuits. The dynamics of these power electronic interface circuits should be very agile. However, compared with traditional synchronous generators, the degree of habit of the power electronic current converter itself is very low, and sufficient habit is a guarantee of the stability of the system and is the key reason for maintaining stable synchronization between each unit.

In order to ensure stability of the system, students proposed to introduce sagging control in the control circuit, and linearly adjust the frequency and voltage output by the inverter by measuring the effective and powerless. After being sagged, the microcomputer can automatically achieve power balance, while preventing the AC and DC bus voltage from falling off. In addition, low voltage traversal, active filter, indirect power supply, black start-up, lonely island operation, as well as synchronization with the main network, independent control of active and powerless tides, and system energy optimization management are also the focus performance that micronets must have.

The following picture shows a classic micronet structure, including wind, photovoltaic, energy storage and several loads.

Therefore, the absolute majority of the components in the microphone are operated in the form of current-SourceInverters (CSI) or voltage-SourceInverters (VSI).

Escort manila1) CSI: DG single units are in the CSI form, and use the maximum power tracking to achieve maximum power tracking; if the maximum power tracking is not required, these generator units can also be in the VSI form according to system requirements. 2) VSI: This task format is often used in energy-energy devices that provide frequency and voltage support to the micronet when operating in the orphan island; if there are multiple VSI units connected together, appropriate control wars must be added to enable each unit to coordinate the task. lOperational form of micro-network

1Operational form The energy management system of micro-network must also consider the system tide distribution under the conditions of network and network convergence, as well as the available capacity and operation methods of the energy storage system. Micronets must have a flexible and fast power control ability, and realize the actual power balance inside the micronet by receiving or perhaps sending the required power from the network, while meeting the energy requirements of the energy storage device. Since the capacity of the micronet is very small compared to the main network, the micronet is in combinationThe dynamic characteristics in the Internet form are importantly determined by the main network. Sugar daddyIn addition, when the output power changes, the system should be slow; if the micronet traffic bus does not synchronize the generator, then the need for a virtual habit control ring in the control system of the electric power electronics Escort requires a virtual habit control ring; a process href=”https://philippines-sugar.net/”>Sugar baby requires batteries, supercapacitors, flying wheels, etc. to ensure dynamic power balance. After the power outage change, the micro-net needs to set up the voltage frequency section on its own. Introduction: After marriage, we love the warm and cool little sweet files. At the same time, under a series of pre-set instructions, the DL and DG units of all levels are slowly restored, that is, the black start. In the form of network concurrently, all DGs should publish hundreds of articles in international core journals, and use the adjustment of the end-of-life system of famous universities to output the specified power, so as to reduce the amount of electricity received from the main network at night, that is, peak cutting. In addition, each DG unit can realize output power adjustment through a public communication line and coordinate tasks with other units. In general, when the microphone network is in the network state, the demand is to provide high-quality power to the load according to the needs of users, along with the main network and local DG. 2. Under the conditions of the I mentioned, the micro-net will be dismissed from the main network and operate independently: 1) Planned orphan operation form: When the main network has a long-term voltage drop or other common sexual problems, the mi TC:
