Method for Calculating the Capacity of Solar Power Plants and its Implementation in LabVIEW Environment

Abstract

The paper presents the method for calculating the capacity of an autonomous solar power plant and its components. This method allows considering a load variation during the day as well as specifying the required capacity of the battery and excluding an unjustified overestimation of the power plant component capacities along with the increase in efficiency of the autonomous solar power plant. Formula for determining the required battery capacity of an autonomous solar power plant could be easily generalized for any number of changes in the load schedule steps. Virtual instruments (calculators) for calculating the capacity of an autonomous solar power plant and its components have been developed on the basis of this method in LabVIEW environment. These calculators may have a rather high visibility, ease of use and low memory requirements along with less computing time spent on calculations. The first calculator may allow recalculating capacities of loads on the power plant main supply bus as well as determining the energy consumption of loads per day. The second calculator may be used for determining the required capacity and number of batteries as well as the capacity of the charger, inverters, main supply bus and solar modules along with the solar power plant efficiency.

“…The calculation for incident radiation (P roof,t ) takes the weather factor into account for the power generated by the solar panel since it measures the radiant power received from the sun per area of the incident surface. The calculation for the generated electric power, as devised by Grigory [37], is as follows: As previously discussed, the peak nominal power of the solar panel modeled in this report is 4.08 kWp. The peak power of the solar panel relates to the amount of energy the solar panel is able to produce during the peak-hours of the day, which is considered to be when light intensity is approximately 1,000 W/m 2 or higher [37].…”

The peak power of the solar panel relates to the amount of energy the solar panel is able to produce during the peak-hours of the day, which is considered to be when light intensity is approximately 1,000 W/m 2 or higher [37]. However, the total generated power from the solar panel occurs at or before the solar intensity reaches the peak limit.…”

“…Due to this, the solar irradiance is divided by the peak intensity so that the electric power can be determined as a ratio of the light intensity at the specific time period. The performance ratio pertains to losses in solar panel capacity in account of environmental related inefficiencies influencing the energy conversion performance such as overheating during summer and snow coverage during winter seasons [37]. An experiment conducted by Grigory [37] provides a method for determining the capacity of an autonomous solar power plant and specified that such effectiveness ratios should be as follows:…”

Networked interactive solar panels over the roof photovoltaic system (PVS) and its cost analysis at Tashkent state technical University

“…Electricity generation from solar-cell power plants is used almost all over the world today, and the use of solar panels is constantly growing. This is facilitated by many factors, the main of which are the use of alternative (renewable) energy sources, which have recently become increasingly relevant and the complete absence of any moving parts, so that their service life is practically unlimited [1][2][3][4]. Solar cell power plants are constantly being improved.…”
