There are three types of micro-netw

There are three types of micro-network loads, namely: sensitive load, adjustable load and intermittent load, connected to feeders A, C and B, respectively. This classification method is the same as for the first level load, the second level load and the third level load in a traditional electrical grid. Feeder A is connected to sensitive and thermal loads. Photovoltaic cells and wind turbines are used to supply electricity to the loads. Due to sudden changes or changes in the voltage of sensitive loads, the loads and equipment on the micro-network will not work or performance will decrease. Therefore, this load must first be satisfied on the micro-network. The micro energy is not connected to feeder B, and the interruptible load connected to it is sent directly through the distribution network. When the network is in a peak or emergency state, it can relieve pressure on the network to keep the network operating smoothly by shutting down these loads. The adjustable load is connected to feeder C, which is driven by a gas turbine and fuel cell. If necessary, this type of load can be adjusted to obtain a balanced power supply.
