“…Já o fornecimento de potência reativa varia entre -147 kvar e 222,625 kvar para as unidades de GS e entre -250 kvar e 188,75 kvar para as unidades de GIDA. As ofertas das unidades de GD e os preços da potência ativa fornecida pela subestação foram baseados em Rueda-Medina e Padilha-Feltrin (2013), Rueda-Medina et al (2014). A partir desses valores, os preços de remuneração da energia, reserva e suporte de potência reativa fornecida pelas unidades de GD variaram de 14,30 R$/kW a 14,90 R$/kW; de 6,44 R$/kW a 6,98 R$/kW; e de 5,44 R$/kW a 5,98 R$/kW, respectivamente, ao longo das 24 horas simuladas.…”

“…Em Zhong e Bhattacharya (2002), foi proposto uma estrutura de licitação de preços, fundamentada nas ofertas dos geradores e compensadores síncronos, para a operação de um mercado competitivo do SA de energia reativa, na qual o operador da RDEE é o único comprador e definidor do preço da energia reativa através do leilão de preço uniforme. Em Rueda-Medina et al (2014), foi analisado a utilização da GD para prestar o SA de reserva de potência ativa para controle de frequência, além de atender as demandas e perdas da RDEE, a fim de minimizar os custos de operação desta rede para o seu operador. Já em Rueda-Medina e Padilha-Feltrin (2013), foi proposto um procedimento de liquidação para um mercado de energia reativa a partir da GD em RDEEs, com intuito de minimizar os custos pagos pelo operador desta rede às unidades de GD pelo fornecimento de energia reativa, as perdas nas linhas de distribuição de energia elétrica e um índice de perfil de tensão.…”

In this work, the use of Distributed Generation (DG) in Eletrical Energy Distribution Systems (SDEEs) to provide ancillary services (SAs) of active power reserve for frequency control and reactive power support for voltage control, and assist the substation in providing power to meet the demands of the loads and system losses, was analyzed. In this context, a model of remuneration of the DG units was elaborated, based on their price offers to supply the SAs mentioned above and the demands of the loads, in which the Electric Energy Distribution Concessionaire (CDEE) is the only buyer. This model differs from the strategies adopted in the Brazilian Electric System (SEB), in which SAs are provided through electricity transmission networks and their remuneration is based on charges determined by the National Electric Energy Agency (ANEEL). The simulations were performed using the A Mathematical Programming Language (AMPL) software, using the Interior Point Optimizer (IPOPT) solver. The SDEE employed in these simulations was the modified 37-node radial distribution test system from the Institute of Electrical and Electronic Engineers (IEEE). From the results obtained, the reduction in total costs between the system without DG units and with these generators was 41.53%. Furthermore, active and reactive power losses decreased by around 98.31% and 97.3%, respectively. These values suggest the possible benefits that DG and their remuneration based on a competitive market can promote to SEB, to CDEE and, consequently, to the final consumers of electricity.Resumo: Neste trabalho, foi analisado o uso de Geração Distribuída (GD) em Sistemas de Distribuição de Energia Elétrica (SDEEs) para prover os Serviços Ancilares (SAs) de reserva de potência ativa para controle de frequência e suporte de potência reativa para controle da tensão, e auxiliar a subestação no fornecimento de potência para atender as demandas das cargas e as perdas do sistema. Nesse contexto, elaborou-se uma modelagem de remuneração das unidades de GD, alicerçada em ofertas de preços destes para suprir os SAs citados acima e as demandas das cargas, na qual a Concessionária de Distribuição de Energia Elétrica (CDEE) é a única compradora. Essa modelagem difere-se das estratégias adotadas no Sistema Elétrico Brasileiro (SEB), no qual os SAs são prestados através das redes de transmissão de energia elétrica e têm sua remuneração fundamentada em encargos determinados pela Agência Nacional de Energia Elétrica (ANEEL).

“…However, with the increasingly penetration of distributed resources, the DSO can have an important role in the frequency control in the future, especially in the regulation and spinning reserve [41]. In [42], it is presented the application of distributed generation to provide ancillary services to control the frequency. The FO could also participate in this service that the DSO will need in the future operation of the power system.…”

a b s t r a c tElectric vehicles can become integral parts of a smart grid, since they are capable of providing valuable services to power systems other than just consuming power. On the transmission system level, electric vehicles are regarded as an important means of balancing the intermittent renewable energy resources such as wind power. This is because electric vehicles can be used to absorb the energy during the period of high electricity penetration and feed the electricity back into the grid when the demand is high or in situations of insufficient electricity generation. However, on the distribution system level, the extra loads created by the increasing number of electric vehicles may have adverse impacts on grid. These factors bring new challenges to the power system operators. To coordinate the interests and solve the conflicts, electric vehicle fleet operators are proposed both by academics and industries. This paper presents a review and classification of methods for smart charging (including power to vehicle and vehicle-to-grid) of electric vehicles for fleet operators. The study firstly presents service relationships between fleet operators and other four actors in smart grids; then, modeling of battery dynamics and driving patterns of electric vehicles, charging and communications standards are introduced; after that, three control strategies and their commonly used algorithms are described; finally, conclusion and recommendations are made.

This article describes a novel power system architecture and operational concept which is founded on the idea of organising sets of distributed generators, loads, storages and multimodal interfaces at distribution level in supervised and controlled grid subsections called smart power cells, which are controllable entities intended to enforce the stability of the transmission network and participate in its operation. Further, the article addresses a control scheme which can be implemented within a smart power cell to control its active and reactive power exchange with the transmission network following set points provided by a superimposed control system, and thus participate in the operation of the transmission grid (e.g. participation in congestion management, system optimisation, balancing of generation and load). The dynamic behaviour of a future power system under consideration of the proposed system architecture including several smart power cells controlled with the developed control scheme is demonstrated through time-domain simulation using a combined transmission-distribution power system model.
