The invention provides a load reduction method for realizing power supply reliability of an independent micronet power supply system. The independent micronet system is divided into different feeding line regions; a main control power supply adopts a centralized access way and is connected with different feeding line regions via a transformer; the independent micronet system further comprises a renewable energy generator and / or an energy storage device and is arranged on a bus bar connected with the high voltage side of the transformer or arranged in the feeding line regions; and interruptible loads in the micronet power supply system are determined, and a load reduction table is constituted according to the quantity of active loads from small to large and / or according to the degree of importance from low to high. Under the situation that renewable energy has the characteristics of randomness and intermittence, in the planning design of the independent micronet system, the renewable energy can be fully used, and the power supply reliability of the system is simultaneously ensured.
Description
technical field [0001] The invention relates to a method for reducing power supply reliability load of an independent micro-grid power supply system, in particular to a method for reducing power supply reliability load of an independent micro-grid system based on power flow balance. Background technique [0002] With the continuous growth of energy demand, the greenhouse effect has become more and more obvious, and the renewable energy generation technology using wind energy, solar energy, etc. has rapidly become an important means to deal with energy and environmental crises today. The independent micro-grid system can combine various types of distributed power generation units, effectively realize the complementarity of multiple energy sources, and improve the energy utilization rate and power supply reliability of the entire system. In remote and island areas, an independent micro-grid system is one of the effective means to solve their power supply problems. [0003] Re...
