Abstract This paper investigates the fundamental trade-offs involved in designing energy-regenerative suspensions, particular, focusing on efficiency of power extraction and its effect vehicle dynamics control. It is shown that typical regenerative devices making use linear-to-rotational elements can be modelled as a parallel arrangement an inerter dissipative admittance. Taking account adjustable parameters generator, it shown, for given suspension damping coefficient, ratio scales with...
This paper presents a study regarding the development of single-stage single-phase grid-tied photovoltaic (PV) inverter with new Global Maximum Power Point Tracking (GMPPT) technique. The proposed strategy is based on indirect PV array voltage control and allows for reduced number sensors, therefore, increasing system reliability reducing costs. was denominated Sensorless Array Voltage Control (SPVAVC-GMPPT). static dynamic accuracy GMPPT algorithm has been demonstrated to be over 99% under...
This study presents the development, design and performance analysis of a multistring bidirectional solar inverter connected to grid (BSICG). An algorithm for independent global maximum power tracking was both developed implemented, which produced system immune non-uniform irradiation conditions with aim applying such on DC (direct current) microgrids conventional AC (alternating BSICG, is characterised by flow management. The main advantage this proposal thus highlighted as stabilisation...
This paper presents the results of a study concerning design and development grid-tied photovoltaic (PV) inverter with new Global Maximum Power Point Tracking (GMPPT) technique. The main novelty presented concerns GMPPT strategy which is based on principle full scanning output power curve (FS-AC-POWER GMPPT) made possible to implement highly efficient PV deploying only one voltage sensor current sensor. presentation proposed technique, project its control are given thorough detailed...
Neste trabalho são apresentadas duas estratégias para melhorar o aproveitamento na geração de energia solar a partir um sistema fotovoltaico. A primeira delas trata-se da utilização inversor multistring, composto por strings fotovoltaicas conectadas conversores CC-CC Boost extração forma independente. Esses dotados algoritmos MPPT P&O clássicos. segunda estratégia consiste algoritmo especificamente criado detecção do ponto global máxima potência. uma estrutura multistring tem como...
Este artigo traz o projeto e desenvolvimento de um inversor fonte corrente (do inglês, CSI) fotovoltaico multistring estágio único sem transformador, destinado exclusivamente a operar em conexão com rede elétrica. Em virtude do comportamento como CSI, dentro das contribuições presente trabalho tem-se ampliação da literatura deste tipo topologia partir implementação técnicas controle operação potência usuais outras estruturas topológicas. Além disso, sistema proposto foi simulado no PSIM® os...
This paper presents the preliminary results concerning development of a multistring solar inverter system for dc microgrids. The proposed is composed two dc-dc converters as input stage and an ac grid-tied bi-directional full-bridge inverter. Each converter operates with independent MPPT algorithms which are capable extracting maximum power even under shading rapid fluctuations irradiation. Regarding inverter, one can outline that it responsible injection extra amount provided by...
Public Internet forums suffer from excess and abuse, such as SPAM fake news. Centralized platforms employ filtering anti-abuse policies, but imply full trust users. We propose a permissionless Sybil-resistant peer-to-peer protocol for content sharing. Our main contribution is reputation system that moderates and, at the same time, delivers network consensus. can trace parallel with Bitcoin follows: consolidated posts create (vs proof-of-work), likes dislikes transfer transactions), aggregate...

This paper presents the initial results and achievements obtained from an ongoing pilot project that consists on real-time monitoring of E-Redes's primary substations (high-voltage to medium-voltage) grounding transformers. By measuring just currents both sides equipment (busbar ground connections), some diagnostic variables were developed in order provide a mean evaluate these type asset condition.
