Problems solved by technology
[0003] However, most of the current smart distribution network evaluation systems focus on the stability of the grid structure and the impact of renewable energy access in the index setting, and do not have any impact on the operation of the smart distribution network connected to the micro-synchrophasor measurement (PMU) device. Evaluate the level and effect of coordinated operation of PMU devices

The invention relates to an evaluation control method for an intelligent power distribution network comprising a micro PMU device. An existing intelligent power distribution network evaluation systemdoes not evaluate the influence of access of a miniature PMU device to an intelligent power distribution network. According to the method, an evaluation system is constructed from the aspects of safety, reliability, economy and interactivity, subjectivity and objectivity are considered, indexes are weighted through a network analysis method-improved entropy evaluation method, the scoring standardof the indexes is set, and the score of each upper-layer index and the total score of the power distribution network are obtained by determining the value of each lower-layer index. According to the method, the operation level of the intelligent power distribution network accessed to the micro PMU device and the coordinated operation effect between the PMU devices can be comprehensively evaluated,so that the supporting effect of the micro PMU device on the intelligent power distribution network can be scientifically evaluated, and an auxiliary decision is provided for the construction investment of a future power grid.
Description
technical field [0001] The invention relates to the technical field of intelligent distribution network, in particular to an evaluation control method for an intelligent distribution network containing a micro PMU device. Background technique [0002] With the development of smart grid technology, the integration of large-scale distributed power into the distribution network and the rapid growth of electric vehicle charging load, the interaction between power grid and user supply and demand is becoming more and more frequent, which makes the distribution network appear two-way flow, intelligent source and load, and network power. With new features such as electronization, the source, network, and load of the distribution network have strong temporal and spatial uncertainties, showing normalized random fluctuations and intermittency. In response to the development needs of distributed power sources, electric vehicle charging and swapping facilities, and demand response resour...
