This paper presents an efficient security assessment system for validating power system operation planning, which has been used in Henan provincial power grid in China. Daily operation planning is to schedule unit commitment and to dispatch generator output economically considering next day generators and transmission components' maintenance planning. The security assessment for validating the daily...
This paper presents an early warning and preventive control system for dynamic security, which has been used in several provincial power grids in China. The framework and the main modules of the proposed system are introduced. The system architecture is based on a Multi-agent system which is developed by our team. The modules like on-line contingency assessment, total transfer capacity evaluation,...
In order to meet the requirements of some important field site applications, IEC61970 Common Information Model (CIM) standard has been extended in China, such as extensions of external network equivalent model and HVDC model. The extended CIM has been applied in many Chinese Electrical Power Control Centers (EPCCs) successfully. As an example of integration of applications developed by different vendors...
In order to make the platform more effective, reliable and flexible, multi-agent technology has been used to construct a distributed computing platform for New generation of EMS (N-EMS) in this paper. Staged Event Driven Architecture (SEDA) model and cluster-computing technology are proposed to implement the agents for a single function, and then taking Blackboard model as a media, these agents are...
This paper introduces a PC cluster based supporting platform, called wide logic grid (WLGrid), for new generation of EMS. This platform has an open and loosely coupling plug-in architecture, which allows components developed individually to be easily plugged into the system. A component-based development (CBD) pattern is used to develop this platform, which can make software modules loosely coupled...
