doi:10.3969/j.issn.1000－7229.2020.03.003

Abstract

Abstract: Aiming at the problem that the existing distribution network planning method fails to fully consider cooperative support for power supply reliability from primary and secondary equipment of distribution network under the ubiquitous power internet of things, a collaborative planning method for distribution network grid structure and distribution automation terminal is proposed. Firstly, an alternate optimization framework for primary and secondary collaborative planning of the distribution network is proposed, and a mathematical optimization model of the network structure planning layer and the automation terminal configuration layer is proposed. Secondly, to solve the reliability problem in the planning and configuration model, combining the types and communication methods of distribution automation terminals, the reliability evaluation method of distribution network considering distribution automation is proposed. Thirdly, the solution method of bi-layer model based on genetic algorithm and integer particle swarm algorithm is proposed. Among them, the efficient generation method for the initial network structure and the corresponding genetic coding method based on the idea of "avoiding the circle method" are proposed in the network structure planning layer. Finally, a certain 60-node city distribution network is used as an example to verify the effectiveness and rationality of the proposed method.

Key words: distribution network, network structure planning, distribution automation terminal, alternate optimization, avoiding the circle method
