O presente trabalho descreve o desenvolvimento de um simulador para o dimensionamento de sistemas solares fotovoltaicos ligados à rede elétrica, para clientes com contracto em baixa tensão nominal, baixa tensão especial e média tensão, para Cabo Verde. O simulador permite ao utilizador o dimensionamento para dois casos, um com base no consumo médio diário do cliente (00:00H às 23:00H), e outro com base no consumo médio durante o período de insolação solar (06:00H às 18:00H), com o propósito de maximizar o potencial renovável.
Para os dois cenários, é avaliado o risco de injecção ou não da energia excedente produzida pelo sistema fotovoltaico na rede elétrica.
O desenvolvimento do simulador foi feito utilizando a linguagem de programação java no ambiente de desenvolvimento Netbeans. O desenvolvimento do mesmo foi feito com recurso a uma interface gráfica com o usuário (GUI), em que o usuário possa interagir com o simulador, preenchendo alguns dados de entrada, que servirão de registo do cliente e de base para o dimensionamento do sistema solar fotovoltaico, tais como: nome de usuário, tipo de cliente, tipo de simulação, ilha, energia consumida e módulo fotovoltaico. Este simulador é programável possibilitando ao utilizador ter as seguintes saídas: potência do painel solar fotovoltaico, potência do inversor, quantidade de painéis fotovoltaicos, ângulo de inclinação de painéis, investimento previsto do sistema, custo economizado, período de retorno de investimento, bem como a emissão evitada de CO2 para a atmosfera.
Deste modo, este simulador constitui uma mais-valia para qualquer usuário ligado à rede com contrato em baixa tensão nominal, baixa tensão especial e média tensão, ´´leigo´´ na matéria, possibilitando-o a ter uma ideia de como vai ser seu sistema, antes de consultar um técnico especialista ou uma empresa da área renovável e com o objetivo de prever o sistema a ser instalado, bem como ter ideia da ordem do valor do custo de investimento.
The present work describes the development of a simulator for the dimensioning of photovoltaic solar systems connected to the electricity grid, for customers with a contract in nominal low voltage, special low voltage and medium voltage, for Cape Verde. The simulator allows the user to design for two cases, one based on the average daily consumption of the customer (00:00H to 23:00H), and the other based on the average consumption during the period of solar insolation (06:00H to 18:00: 00H), with the aim of maximizing the renewable potential. For both scenarios, the risk of injecting or not the excess energy produced by the photovoltaic system into the electricity grid is evaluated. The development of the simulator was done using the java programming language in the Netbeans development environment. Its development was done using a graphical user interface (GUI), in which the user can interact with the simulator, filling in some input data, which will serve as a customer record and as a basis for the design of the solar system. photovoltaic system, such as: user name, customer type, simulation type, island, energy consumed and photovoltaic module. This simulator is programmable allowing the user to have the following outputs: photovoltaic solar panel power, inverter power, number of photovoltaic panels, panel inclination angle, expected system investment, cost saved, payback period, as well as the avoided emission of CO2 to the atmosphere. In this way, this simulator is an asset for any user connected to the network with a contract in rated low voltage, special low voltage and medium voltage, ´´layman´´ in the matter, allowing him to have an idea of how his system, before consulting a specialist technician or a company in the renewable area and with the objective of predicting the system to be installed, as well as having an idea of the order of value of the investment cost.
