摘要
针对现有配电网规划方法中未能充分考虑到泛在电力物联场景下一二次协同支撑供电可靠性的问题,提出了一种配电网网架结构与配电自动化终端协同规划方法。首先,提出配电网一二次协同规划的交替优化框架,构建了网架规划层与自动化终端配置层的优化数学模型;其次,针对规划配置模型中可靠性求解问题,结合配电自动化终端类型与通信方式,提出考虑一二次协同的配电网可靠性评估方法;再次,提出了基于遗传算法和整数粒子群算法的双层模型求解方法,其中在网架规划环节提出了基于"避圈法"思想的初始网架高效生成方法及相应的遗传编码方法;最后利用某60节点城市配电网作为算例验证了所提方法的有效性与合理性。
Aiming at the problem that the existing distribution network planning method fails to fully consider cooperative support for pow er supply reliability from primary and secondary equipment of distribution netw ork under the ubiquitous pow er internet of things,a collaborative planning method for distribution netw ork grid structure and distribution automation terminal is proposed.Firstly,an alternate optimization framew ork for primary and secondary collaborative planning of the distribution netw ork is proposed,and a mathematical optimization model of the netw ork 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 netw ork considering distribution automation is proposed.Thirdly,the solution method of bi-layer model based on genetic algorithm and integer particle sw arm algorithm is proposed.Among them,the efficient generation method for the initial netw ork structure and the corresponding genetic coding method based on the idea of"avoiding the circle method"are proposed in the netw ork structure planning layer.Finally,a certain 60-node city distribution netw ork is used as an example to verify the effectiveness and rationality of the proposed method.
