【摘要】：隨著電力系統(tǒng)的發(fā)展,分布式能源越來越多的嵌入到電網(wǎng)中,IBDGs(Inverter-Based Distributed Generators)的高滲透率,使得配電系統(tǒng)已成為一個非常復(fù)雜的網(wǎng)絡(luò)。傳統(tǒng)的配電網(wǎng)無法有效的管理IBDGs,這使得IBDGs的利用率很低。CIGRE C6.11工作組提出的主動配電網(wǎng)可通過高度自動化電氣設(shè)備及先進的通信技術(shù)將IBDGs與大型配電網(wǎng)緊密關(guān)聯(lián),其有很強的對IBDGs接入和控制能力,并可以極大地提高IBDGs利用率。配電網(wǎng)故障越來越多的發(fā)生在電力系統(tǒng)中,顯著降低了電力系統(tǒng)的穩(wěn)定性及電能質(zhì)量。為了降低電力故障對電力系統(tǒng)的影響,有效控制IBDGs并提高IBDGs利用率,本文著重研究了含IBDGs主動配電網(wǎng)故障自愈。本文主要研究工作如下:1、為了有效管理IBDGs,本文中逆變器的控制策略采用的是下垂控制。為了彌補其不足,本文提出將相角下垂控制與下垂控制融合在一起,實現(xiàn)了IBDGs并網(wǎng)運行和孤島兩種運行模式的平滑無縫切換。2、含IBDGs主動配電網(wǎng)運行期間,會產(chǎn)生大量成分復(fù)雜且多態(tài)的數(shù)據(jù)。傳統(tǒng)的數(shù)據(jù)處理技術(shù)已不能滿足需求,本文提出用大數(shù)據(jù)處理方法來處理含IBDGs主動配電網(wǎng)運行期間產(chǎn)生的數(shù)據(jù)。仿真結(jié)果表明,這一數(shù)據(jù)處理方法有著非常好的效果。3、針對含IBDGs主動配電網(wǎng)可能出現(xiàn)的三相接地故障,傳統(tǒng)的故障自愈方法無法快速、有效地恢復(fù)盡可能多的失電負荷�；诖�,本文提出將先進的智能代理技術(shù)用于含IBDGs主動配電網(wǎng)故障自愈中。4、為解決MAS(Multi-agent System)與IEC 61850的兼容問題,本文將IEC 61850信息模型映射到代理通信語言ACL上。通過將IEC 61850信息模型作為代理間信息交互的統(tǒng)一模型以實現(xiàn)不同智能電子設(shè)備之間的通信,代理之間的信息交互用ACL語言。本文提出的基于MAS的含IBDGs主動配電網(wǎng)故障自愈功能模型,能夠非常靈活、非常迅速、非�？煽康刂贫ü╇娀謴�(fù)方案,其降低了故障自愈所需時間,增強了系統(tǒng)的安全性、可靠性,提高了系統(tǒng)的電能質(zhì)量,避免了IBDGs不必要的功率削減。5、本文提出利用MACSimJX這個中間件來實現(xiàn)MATLAB/Simulink平臺與JADE平臺這兩個平臺之間的通信,通信仿真結(jié)果證明了這種通信機制的可行性和準(zhǔn)確性。然后分別在MATLAB/Simulink搭建了含IBDGs主動配電網(wǎng)故障自愈仿真模型和在JADE中構(gòu)建了MAS。通過使用MATLAB/Simulink仿真模型中仿真的數(shù)據(jù),利用Relays的功能實現(xiàn)了故障定位、識別及隔離,仿真結(jié)果表明Relays具備很高的故障分類精度。通過MAS制定故障恢復(fù)方案,最終在MATLAB/Simulink仿真模型中實現(xiàn)了含IBDGs主動配電網(wǎng)故障自愈。實驗結(jié)果表明,本文提出的含IBDGs主動配電網(wǎng)故障自愈系統(tǒng)具備很好的可靠性及穩(wěn)定性。
[Abstract]:With the development of power system, more and more distributed energy is embedded in the power network, which makes the distribution system become a very complex network. The traditional distribution network can not manage IBDGs effectively, which makes the IBDGs utilization rate very low. CIGRE C6.11 working group put forward the active distribution network, which can connect IBDGs closely with large distribution network through highly automated electrical equipment and advanced communication technology. It has a strong ability to access and control IBDGs, and can greatly improve the utilization of IBDGs. Distribution network faults occur more and more in the power system, which significantly reduces the stability and power quality of the power system. In order to reduce the influence of power failure on power system, effectively control IBDGs and improve the utilization rate of IBDGs, this paper focuses on the self-healing of active distribution network with IBDGs. The main work of this paper is as follows: 1: 1. In order to manage IBDGs effectively, the droop control strategy is adopted in this paper. In order to make up for its deficiency, this paper proposes to combine the phase angle droop control and droop control together to realize smooth seamless switching between IBDGs grid-connected operation mode and island-isolated operation mode, including the IBDGs active distribution network operation period. A large number of complex and polymorphic data are generated. The traditional data processing technology can not meet the demand. In this paper, the big data processing method is proposed to deal with the data generated during the operation of the active distribution network with IBDGs. The simulation results show that this data processing method has a very good effect. For three-phase grounding faults that may occur in active distribution network with IBDGs, the traditional fault self-healing method can not quickly and effectively recover as much power loss as possible. In order to solve the compatibility problem between MAS (Multi-agent System) and IEC 61850, the IEC 61850 information model is mapped to the agent communication language ACL in order to solve the compatibility problem of MAS (Multi-agent System) and IEC 61850. The IEC 61850 information model is used as the unified model of information exchange among agents to realize the communication between different intelligent electronic devices. The information exchange among agents is based on ACL language. The fault self-healing function model of active distribution network with IBDGs based on MAS is presented in this paper. It can make the power supply recovery scheme very flexible, very fast and very reliable. It reduces the time required for fault self-healing and enhances the security of the system. Reliability improves the power quality of the system and avoids unnecessary power reduction of IBDGs. This paper proposes using MACSimJX middleware to realize the communication between MATLAB/Simulink platform and JADE platform. The simulation results show the feasibility and accuracy of the communication mechanism. Then the fault self-healing simulation model of active distribution network with IBDGs is built in MATLAB/Simulink and the masse is constructed in JADE. By using the simulation data of MATLAB/Simulink simulation model and the function of Relays, the fault location, identification and isolation are realized. The simulation results show that Relays has high fault classification accuracy. The fault recovery scheme is established by MAS, and the fault self-healing of active distribution network with IBDGs is realized in the simulation model of MATLAB/Simulink. The experimental results show that the fault self-healing system with IBDGs in active distribution network has good reliability and stability.
