Abstract

The invention discloses a novel optimal capacity allocation method for a mobile emergency power supply in an urban distribution network based on an improved quantum-inspired evolutionary algorithm (QEA). The method comprises the following steps: 1) inputting initial parameters; 2) analyzing a typical day; 3) setting initial parameters of the QEA; 4) obtaining optimized parameters by adopting an inner optimization method; 5) calculating a particle adaption value; 6) updating a local optimal vector and a global optimal vector; 7) updating a particle position value by using a biological evolution rule; 8) performing local search; 9) inspecting the astringency; and 10) outputting the result. The invention provides a novel capacity allocation method for a mobile emergency power supply based on double-layer optimization in combination with the improved QEA.

Description

technical field [0001] The invention relates to a method for configuring the capacity of a mobile emergency power supply based on an improved quantum evolutionary algorithm, in particular to the optimal configuration of capacities of different types of emergency power supplies in a power supply station containing the mobile emergency power supply. Background technique [0002] With the strengthening of distribution network construction and the maturity of micro-grid technology, the penetration rate of distributed generation (DG) in the power grid continues to increase. With the continuous development of urban distribution network, the network structure becomes larger and larger. Once a large-scale power outage occurs, if corresponding emergency measures are not taken in time, it will bring huge economic losses to urban load users. The emergence of mobile emergency power supply can directly restore the power supply of the feeder connected in the distribution network, and solv...
