Renewable energy has the advantages of renewability and high temperature and has great potential for development, but its instability limits its large-scale promotion. Aiming at the stable operation of the new energy power system and ensuring the safe and reliable operation of the power grid, this project defines the basic topology of the variable multiple DC/DC converter according to the idea of switching circuit parallel factor or reducing ripple under each duty cycle. Secondly, the system structure under the boost mode is modeled, and the system is optimized by the combination of a single closed-loop current balance and duty cycle feedforward control. Finally, the model is simulated, and the results show that the method is correct and reasonable.

A principal contribuição deste trabalho é apresentar uma proposta para o desenvolvimento do controle das potências ativa e reativa de um sistema de geração de energia eólica conectado à rede elétrica, utilizando o gerador de indução trifásico com rotor gaiola de esquilo (GIGE). Os terminais do estator do GIGE são conectados à rede elétrica antes do filtro indutivo usando uma topologia de conversor eletrônico de potência CA/CC/CA, denominada back-to-back, enquanto os terminais do rotor estão curto-circuitados. O controle do conversor do lado da rede (CLR) é apresentado, sendo responsável pelo controle de potência e também por manter constante a tensão do barramento CC. O controle do conversor do lado da máquina (CLM) também é apresentado, no qual o controle vetorial é utilizado nas variáveis do rotor, para que o GIGE seja controlado através das referências de torque e corrente de magnetização. O sistema estudado foi matematicamente modelado e simulado usando o software Matlab / Simulink.

The standalone solar power system has long been used to meet the electrical needs of basic building structures. To counter the natural supply–demand imbalance caused by solar energy, standalone solar PV system often include energy storage devices, primarily lead–acid batteries. Due to lead-acid battery limitations, solar systems often have higher operational costs compared to traditional power systems. It has been discovered that a supercapacitor-battery hybrid energy storage device can be used to prolong the cycle life of a battery system by reducing the charge–discharge stress caused by variable power exchange. This research examines the influence of a supercapacitor on a photovoltaic system that makes use of a hybrid energy storage system that includes both batteries and supercapacitors in order to lessen the stress placed on the batteries. The methodology involves data collection for load profile and meteorological information, designing solar PV system, and simulation using Matlab SIMULINK to study the effect of supercapacitor on battery current of the evaluated system. Three different energy storage system topologies in building applications were simulated, and their ability in managing battery stress was investigated and evaluated. From the result, it is clear that by applying passive HES system, 53% of battery current can be reduced compared to battery-only system and 92% of reduction can be achieved by using semi-active HES system.
