The Research On The Effect Of Large Integration Of Microgrid On The Power Angle Stability Of The System

With the increasingly serious energy situation, the increasing pressure for China’scarbon emission from the international community, the increasing pressure of publicopinion, social life and production of the power system security and reliability of theincreasing demand, micro-grid as an effective means to deal emerged. Rationalorganization of micro-grid energy make use of distributed power generation, togetherwith its load to form a unified, coordinated, and made with organic whole, with a largegrid interconnection and the island under two operation modes, and this unprecedentedlychanges the power system power supply mode, the system flow distribution, powerquality, and power system security and stability issues of most concern. Highpermeability under the micro-grid access through the electrical interface according totheir amount of variation of the relative change their system equivalent impedance,regulation and the trend of exchange system, thereby affecting the system’s internalgenerator power angle and voltage stability. Introduction This chapter briefly describesthe high permeability and stable micro-grid system, the impact of access on the status ofbasic research, and briefly describes the contents of this rough work; This chapterdescribes the typical micro-grid distributed power within the various construction moldand characterization, and the establishment of a complete micro-grid model; this chapterfocuses on micro power grid distributed power control strategy, including a summary ofthe traditional micro-power control strategy and more superiority of the proposednonlinear control strategy and performance comparison; this article puts forward a fourthanalysis of the high penetration of grid access under the micro-grid stability of a unifiedapproach, and for the interface characteristics of the proposed model based on access tomicro-grid system angle stability analysis of the impact calculations and simulation; thischapter is mainly theoretical and simulation analysis of the high permeability of the nextmicro-grid power angle stability of the interconnected power system as a whole, andultimately concluded.
