Power grid energy management system (EMS) based on service component architecture

Abstract

The invention relates to a power grid energy management system (EMS) based on service component architecture. Service units which form the EMS are divided into fine-grain atomic service units for sorting analysis, linear equation set solution, nonlinear equation set solution, optimal calculation and the like. Coarse-grain functional service units for real-time monitoring, history information management, model management, SCADA (Supervisory Control And Data Acquisition), IEEE model analysis, CIM (Common Information Model) model analysis, dispatching management, real-time dispatching, dispatching planning, automatic power generation control, safety evaluation, advanced application, dispatcher training simulation, topological analysis, state estimation, load flow calculation, optimal load flow and the like are formed through data exchange, analysis and processing among the atomic service units. Finally, the EMS with complete functions is formed by the function service units according to an agreed calling method. By dividing the EMS into the atomic service units, the extensibility, flexibility, openness and elasticity of the system are guaranteed and enough spaces are reserved for the development and upgrade of the EMS.

Description

technical field [0001] The invention belongs to the field of power system control, and in particular relates to an implementation scheme of a power grid energy management system based on a service component architecture. Background technique [0002] The Energy Management System (EMS system) is a computer-based comprehensive automation system in the modern power system. The core system of the grid dispatching center. [0003] At present, all mainstream EMS products were developed in the 1990s. In view of the scale of the power system at that time, and limited by the theoretical level of the power system, computer technology, control theory and technology at that time, its function is mainly to help dispatchers monitor and control. Analyze the health of the grid. With the continuous expansion of the grid scale, the continuous enrichment of the diversity of power system resources, the continuous maturity of smart grid from conceptual theory to realization technology, the con...

AI Technical Summary

Problems solved by technology

At the same time, the implementation of each coarse-grained service unit is still developed according to the previous model of "independent construction, customized development", and the flexibility and scalability of the service unit have not been fully utilized.

It shows that the application of the energy management system to the service unit architecture is still in its infancy, does not involve deeper and more detailed service unit segmentation, and fails to make full use of the excellent flexibility and openness provided by the service unit component architecture
