Research On Indices Of Intelligent City Network Planning Evaluation

With the development of smart grid construction in our country, the related planningof smart grid has been drawing up in many cities. So the scientific and reasonableevaluation for planning is the primary responsibility after the formulation of planningscheme. The establishment of evaluation index is the most key part in the whole processof evaluation, and the scientific and reasonable evaluation index has the importantinfluence for evaluating results. Therefore, the evaluation index system of distributionnetwork intelligent planning and city smart grid planning post evaluation system isestablished in this paper, the specific researches as follows:Firstly, combining the key technology of smart grid, the evaluation index system ofdistribution network intelligent planning is established on the basis of the contents ofChina’s distribution network intelligent planning which is divided into: intelligentinfrastructure index and performance index. The infrastructure index contains thecommunication systems, primary station, intelligent terminal/subside and planningevaluation index of distributed generation access capacity. The performance index analyzethe distribution network intelligent planning which are worth the investment andimplementation from the aspects of power grid performance, economic benefit and socialbenefit, and the specific meaning of each index are introduced.Then, the method of analytic hierarchy is used to calculate the weight and the methodof fuzzy comprehensive evaluation is used to evaluate in a city of intelligent powerdistribution network planning project, and the results of evaluation prove that theevaluation index system is effective and feasible.Finally, establishing a set of urban smart grid planning post evaluation index systemin this paper, and the process steps of the post evaluation is given. The index system isused to supervise and inspect the schedule and scale of the planning implementationprocess, and play a certain role in promoting the smart grid planning for the futureimprovement of evaluation, and make smart grid planning and construction in the correctdirection.
