Texto completoEn stor integration av solceller (PV) och vindkraftverk i distributionsnät innebär nya utmaningar på olika nivåer. En av dem är en ökande spänning i lågspänningsnät (LV) samt på mellanspänning (MV), orsakad av distribuerad generering. Detta kan leda till spänningar över högsta tillåtna värde av 110% av nominell spänning.Det finns olika sätt att mildra detta problem. Dessa sträcker sig från dyra nätförstärkningar, som förstärkta linjer eller installation av lindningskopplare (OLTCs) i distributionstransformatorer, till spänningsstyrning av de distribuerade generatorerna. En av dessa spänningsstyrningar är förbrukningen av reaktiv effekt i solcellernas växelriktare. Denna styrning kan sänka spänningen lokalt men den har också en inverkan på andra noder i elnätet. En rad möjligheter finns, oftast med hjälp av en aktiv-effekt-beroende reaktiv effekt (cos φ(P)-styrning) eller med hjälp av en spännings-beroende reaktiv effekt (Q(U)-styrning). Dessa kan antingen styras med hjälp av lokala insignaler eller innebära någon form av samordnad styrning, som vanligtvis medför att en kommunikationsinfrastruktur måste byggas upp. I denna avhandling har två MV-nät, vilka ligger nära Worms, Tyskland, modellerats och validerats med mätdata som tillhandahållits av det lokala distributionssystemets operatör. Längs de två MV-näten, har totalt tre lågspänningsnät modellerats i detalj. Effektiviteten av en lokal Q(U)-styrning med en död-zon har jämförts med det värsta fallet, där ingen reaktiv effektstyrning tillämpas och med bästa fall, där alla PV-omriktare maximalt har deltagit i den reaktiva effektstyrningen. Dessa inställningar testades sedan för olika scenarier för ökad mängd PV. Dessutom har effekterna av Q(U)-styrning på andra LV-nät, som ligger på samma MV-nät, analyserats. Resultaten visar: i) Generellt har de undersökta LV-näten redan stora PV-installationer och stor resulterande back-matning under tider med hög PV-produktion. Mängden PV kan dock fortfarande ökas väsentligt, framför allt på LV-linjer som för närvarande endast har låg eller måttlig mängd PV.; ii) Q(U)-styrning med dödband kan öka möjlig mängden PV med ca 20 - 33% för de undersökta elnäten. Möjlig ökning kan dock variera mycket mellan olika elnät och olika pridning av PV; iii) på grund av den studerade Q(U)-styrningen så varierar den reaktiva effektproduktionen kraftigt mellan olika PV-anläggningar i de undersökta elnäten. Detta minskar en rättvis fördelning med denna metod och kompensations-mekanismer kan behövas. Emellertid har ingen kvantifiering av detta gjorts, iv) Det bästa fallet visar att bra reaktiv effekt-styrning skulle ha en mycket hög potential, så samordnad spännings-styrning skulle avsevärt kunna öka möjlig mängd PV.

Este trabalho, realiza uma revisão da metodologia tradicional, de representação dos limites de geração de potência reativa, na solução do problema de fluxo de potência, em coordenadas polares, pelo método de Newton-Raphson. Apresenta uma nova modelagem para o tratamento destes limites, baseada em uma formulação full Newton do problema. Para tanto, utiliza-se um conjunto de chaves sigmoides, que incorporam novas equações à matriz Jacobiana, de acordo com a geração de potência reativa da barra. De forma a tornar o sistema possível e determinado, a geração de potência reativa, é tratada como uma nova variável de estado do problema, corrigida a cada iteração do método de Newton. A formulação proposta, utiliza duas chaves sigmoides para o tratamento dos limites de geração de potência reativa, em barras PV e, duas chaves, que consideram o procedimento de retomada do controle (conhecido como estratégia de backoff ), das barras que atingiram limites, caso necessário. Dessa forma, não há uma mudança explícita no tipo da barra, como na metodologia tradicional, e a dimensão da matriz Jacobiana é mantida constante. Neste trabalho, todo o equacionamento e formulação, foi desenvolvido através do programa Matlab, e os resultados foram validados, utilizando-se o programa de análise de redes – ANAREDE, versão acadêmica, disponibilizada pelo Centro de Pesquisas de Energia Elétrica (CEPEL). São avaliados alguns sistemas benchmark IEEE e os resultados obtidos, demonstram a eficácia das formulações propostas.
This work, presents a review of the traditional methodology, of representing the limits of reactive power generation, in the solution of the power flow problem, in polar coordinates, by the Newton-Raphson method. Presents a new modeling for the treatment of these limits, based on a formulation full Newton of the problem. For this purpose, a set of sigmoid switches is used, to incorporate new equations to the Jacobian matrix, according to the generation of reactive power of the bus. In order to produce a system possible and determined, reactive power generation, is treated as a new problem state variable, corrected at each iteration of the Newton’s method. The proposed formulation, use two sigmoid switches for the tratment of reactive power generation limits, in PV buses and also, two switches, that consider the procedure of resumption of control (procedure known as backoff strategy), of the buses that reached some limit, if necessary. Thus, there is no explicit change in the bus type, as in traditional methodology, and the Jacobian matrix dimension is kept constant. In this work, all equation and formulation, were developed through Matlab software, and the results were checked, using the network analysis program – ANAREDE, academic version provided by Electrical Energy Research Center (CEPEL). Some IEEE benchmark systems are evaluated, and the results obtained, demonstrates the efficacy of the proposed formulations.
