Simulation of Energy Input to Solar Panels

Abstract

In article the review of assessment methods of the energy supplied to the surface of solar panels. Need of increase in accuracy of calculation of the solar energy entering on the panel is proved due to accounting of the additional influencing factors. A technique for estimating solar energy to the surface of panels has been developed. The degree of cloudiness influence on the solar energy input for the area under consideration is identified. Comparison of results of modeling with use of the developed technique and specialized computer programs is carried out. The comparison showed satisfactory results. Modeling of incoming solar energy for the existing solar power station showed a higher quality of the developed technique compared with specialized software. The optimal angle of inclination of the solar panel is calculated and the reduction of the incoming energy is analyzed when the angle deviates from the optimal value. The application of modeling of incoming solar energy intake to obtain daily graphs for the electricity generation of a solar power station and comparing them with daily graphs of the electrical load of the consumer is considered. Conclusions by results of researches are drawn.

Basic principles of solar energy

“…En la ecuación (7) se ve que la potencia de salida P aumenta con I pero disminuye con I L −I. Por lo tanto, puede existir una potencia de salida óptima.…”

“…Para 2040, las energías renovables alcanzarán el 34% de la generación de energía en todo el mundo [6]. Al ser una fuente de energía limpia, los sistemas solares pueden desempeñar un papel vital en la reducción de gases de efecto invernadero y pueden reducir considerablemente los efectos del calentamiento global [7]. Las tecnologías de energía solar se utilizan ampliamente en torres de base de telecomunicaciones, bomba de agua, redes inteligentes, microrredes y generación distribuida, sistemas de gestión de edificios, carga de vehículos eléctricos, satélites, aplicaciones marinas, entre otros [8], [9], [10].…”

Towards Optimal Management in Microgrids: An Overview

“…Over the past decades, the planet has experienced a deterioration in the weather conditions and an increase in natural disasters. The aforementioned problems have been discussed at climate conferences [1]. As the energy crisis and environment pollution arise from the great demand for electric energy, one of the solutions to reduce harmful emissions to the environment and demand for electric energy is to reduce the use of fossil energy sources (FESs) and accelerating the use of renewable energy resources (RESs), especially solar energy, which is useful in the production of electric energy through photovoltaic (PV) panels [1,2].…”

There is currently great worldwide interest in assessing: (i) the performance of a PV system, (ii) the price per PV module, (iii) the solar resource of the place of energy generation, etc.…”

“…It is often intended to minimize the operating cost, minimize pollution emissions, and maximize energy production through an objective function. A quadratic objective function model used in many EMSs is shown in Equation (1). Additionally, the net sum of all energy flows can be represented by an energy balance depending on the RESs, the ESSs, and the power of the grid, as shown in Equation (2).…”
