Abstract
With the expanding of power grid scale in Chinese metropolis, the task intensity of power dispatchers increases rapidly in regulation of the power system operation structure and states to deal with everyday scheduled maintenance. In this paper, we propose a knowledge-based intelligent system developed to deal with daily management of the power dispatching plans. The system will analyse all the operation state changing tasks arranged for the next day and group the plans according to their association. It will automatically check the security of each power dispatching plan and generate the corresponding dispatching-order tickets. The proposed system builds up power grid ontology knowledge and first-order logic rules and integrates techniques of knowledge reasoning, natural language understanding and network topology analysis. Application shows that it can effectively realize the day-ahead power dispatching plan management (PDPM) instead of the human dispatchers.
Highlights
With the arrival of the new wave of artificial intelligence (AI), the construction of intelligent system in power system is in sustained growth [1,2,3,4,5,6]
For fast developing metropolis in China, most of the daily workload in power dispatching center comes from the operation modes switch process, which is composed of complicated cross-checking series to ensure the safety of the system
We present an intelligent computer system (IS) for the power dispatching plan management (PDPM), which can take over the task of dispatcher to realize fully automated closed-loop processing of the dispatching plans
Summary
With the arrival of the new wave of artificial intelligence (AI), the construction of intelligent system in power system is in sustained growth [1,2,3,4,5,6]. The papers [9,10,11] propose the ideas of intelligent robot or new paradigm for power dispatching and controlling, they have no further discussion on their designs and implementation. For fast developing metropolis in China, most of the daily workload in power dispatching center comes from the operation modes switch process, which is composed of complicated cross-checking series to ensure the safety of the system. On the day before the execution of the power dispatching plans, the dispatcher needs to check the plans and evaluate their feasibility according to the load-forecast results and the latest system operation states. We present an intelligent computer system (IS) for the power dispatching plan management (PDPM), which can take over the task of dispatcher to realize fully automated closed-loop processing of the dispatching plans. A case test results as well as the discussions are given in section 4 of the paper
