“…As oscilações em baixa frequência são fenômenos oscilatórios que surgem em frequências próximas ao intervalo entre 0,5 a 3Hz. Já as oscilações subsíncronas (SSO) indicam uma volubilidade em frequências que variam de 5 a 55Hz, em sistemas cuja frequência fundamental é 60Hz [14].…”

Nos últimos anos, a temática das interações harmônicas e inter-harmônicas, no âmbito de sistemas renováveis de geração, vem ganhando destaque a partir de considerações acerca da sua dinâmica de controle e chaveamento de conversores. Neste contexto, cresce-se a necessidade de análise da ocorrência de oscilações harmônicas, as quais podem variar desde baixas frequências a elevadas. Assim, modelos computacionais têm sido testados e colocados à prova, com o intuito de avaliar sua representatividade frente aos fenômenos desta natureza. O presente informe técnico tem por objetivo esclarecer de forma simples e direta as diferenças conceituais dos fenômenos de emissão harmônica, além de propor uma revisão bibliográfica detalhada dos principais métodos de modelagem de sistemas eólicos, com foco em estratégias no domínio do tempo. Para tanto, três distintos modelos de aerogeradores serão implementados no simulador Atpdraw. Os parâmetros e medições utilizados como base de comparação dos modelos implementados são reais e advindos de um parque eólicos situado no nordeste do Brasil. De posse dos resultados do estudo proposto é possível concluir que os modelos apresentados podem ser utilizados como ferramentas importantes para análise dos fenômenos de interações harmônicas, e se mostram mais atraentes que os equivalentes de Thévenin e Norton para a representatividade da rede equivalente. Neste parque temse verificado problemas correlatos à queima de equipamentos e mal funcionamentos provocados por interações harmônicas.

“…Lennerhag et al [9] had studied performance indicators such as, disturbance levels of slow voltage variations, overloading, harmonics, flicker, rapid voltage changes, losses, or the number of certain power quality events in the network which can be used for evaluating the impact of renewable energy on power systems. Asadinejad et al [10] had suggested that electricity consumers should be classified and segregated based on demand response and volatility of prices under high renewable penetration which results in minimum technological and economical losses.…”

<p>This paper addresses the impact of renewable power generation such as photovoltaic and wind energy in the existing power system operations. Various modeling approaches and power quality/reliability analysis of these renewable energy sources in the electric power system by researchers and research organisations and utilities are outlined and their impacts are assessed. Challenges and protection schemes of renewable power integration into the existing grid are discussed through a detailed literature review and study of renewable integration into the Indian power system are outlined including potential planning and policy actions to support renewable energy integration in India.</p>

After a brief historical introduction to the hosting-capacity approach, the hosting capacity is presented in this paper as a tool for distribution-system planning under uncertainty. This tool is illustrated by evaluating the readiness of two low-voltage networks for increasing amounts of customers with PV panels or with EV chargers. Both undervoltage and overvoltage are considered in the studies presented here. Probability distribution functions are calculated for the worst-case overvoltage and undervoltage as a function of the number of customers with PV or EV chargers. These distributions are used to obtain 90th percentile values that act as a performance index. This index is compared with an overvoltage or undervoltage limit to get the hosting capacity. General aspects of the hosting-capacity calculations (performance indices, limits, and calculation methods) are discussed for a number of other phenomena: overcurrent; fast voltage magnitude variations; voltage unbalance; harmonics and supraharmonics. The need for gathering data and further development of models for existing demand is emphasised in the discussion and conclusions.An international working group [22] recently presented a number of recommendations, key findings and open issues to be addressed because of the integration of solar power. Recommendations were given for a number of power-quality phenomena, including harmonics, supraharmonics, fast voltage variations (faster than 10-min time scale), slow voltage variations (slower than 10 min), overvoltage, flicker, and voltage unbalance. The hosting capacity approach, as was proposed by an international cooperation project in 2004 (see Section 2) is put forward in the report as an important tool for quantifying the impact of solar power on the power system. Additional work is needed, according to the report, for establishing suitable performance indices and corresponding limits.This paper consists of three main parts. It starts in Section 2 with an overview, partly from a historical insider perspective, of the hosting-capacity approach. This part also includes a discussion on different kinds of uncertainly. A hosting-capacity-based planning approach is presented in Section 3, applied in Section 4.1 through Section 4.6 and discussed in Section 4.7. The description and the application are for overvoltage and undervoltage as these are the phenomena, with the possible exception of overcurrent, for which the best calculation tools, performance indices and limits are available. The third part of the paper contains a detailed discussion about including other phenomena in hosting-capacity studies. For each phenomenon, performance indices, limits and calculation methods are discussed. Hosting CapacityThe term "hosting capacity" was coined in the context of distributed generation by André Even in March 2004 during discussions within the integrated European EU-DEEP project [23,24]. An approach for quantifying the hosting capacity was developed further by others within that same project [25]. The term "hosting capa...
