含大量可再生能源未来电网的建模及控制
Modeling and Control for Future Grids with Large Renewable Energies
摘要
Abstract
Utilizing more active resources on the demand side is one promising strategy to address the problem of operating future grids with large renewable energies.In the integration of increasing load-side resources at all system levels,load-side control and blending of transmission and distribution systems are two major trends that may be utilized in future grid control paradigms.The modeling and control of distributed controllable resources and renewable sources is a significant challenge,as it requires new mathematical models and coordination methods.It is necessary to determine a new network structures and a control paradigm that is cost effective and robust to future changes.This paper will provide an overview of our ideas to address these challenges.The goal of this work aimed to determine the control architectures for bidirectional delivery systems,which can overcome new challenges with greater demand-side and storage participation.A layer-based control paradigm is proposed,every piece of equipment will be accounted and represented by a node or branch in a granulated graph.These allow model layers where nodes represent lower voltage networks to capture'drill-down'modeling from transmission to sub-transmission to distribution in a signal coordinated model.Specific research projects are described related to granular control,frequency control,and voltage control.关键词
