Sumber energi terbarukan mempunyai sifat terbarukan serta berkesinambungan dan pemanfaatan sumber energi terbarukan merupakan alternatif yang perlu terus dikembangkan. Pembangkit Listrik Tenaga Surya (PLTS) menggunakan energi matahari sebagai sumber terbarukan dan mengkonversi energi matahari menjadi energi listrik. Untuk memaksimalkan intensitas matahari yang diterima oleh panel surya maka pada perancangan sistem dibutuhkan sudut kemiringan panel yang paling tepat untuk menerima radiasi matahari yang paling tinggi. Penelitian ini dilakukan untuk mengetahui peningkatan arus keluaran terhadap perubahan sudut kemiringan pada photovoltaic, dengan menggunakan regretion quadratic method. Hasil yang diperoleh pengukuran sudut kemiringan PV dengan arus keluaran menggunakan metode regresi kuadratik sudut optimum peletakan panel sel surya dalam menerima paparan radiasi sinar matahari pada sudut 36.7º, dengan nilai arus keluaran sebesar 1.99 Ampere. Ternyata hasil pengukuran real dibandingkan dengan menggunakan metode regresi kuadratik diperoleh hasil nilai RMSE (root mean sequre error) 0.27476.
The population of the population in big cities, special areas of the big cottage growth continues to increase according to the BPS in 2015 amounted to 2,733,240 and increased in 2019 3,013,851. With an increasing population, it will increase electricity demand in the region. The JS 190 Distribution Station provided a significant increase in transformer loading which achieved a 95.75% loading presentation of a 200 kVA transformer capacity. Therefore it is necessary to improve by looking at these conditions, one of which is by doing an uprating transformer or adding a power transformer with a larger capacity to 400 kVA. From the results of the increase obtained loading results decreased to 52.75% which means the reversal transformer is one method that can be used to overcome the overload.
Load unbalance in an electric power system often occur to meet consumer needs. Distribution of the load that was initially evenly will experience an unbalance when the burdens. As a result, current arises in the transformer neutral, current flowing in the transformer neutral causes losses, losses in the neutral conductor transformer and current flowing to the ground. Technically, if these losses occur continuously, it will be detrimental to PLN and can reduce transformer efficiency. For the supply of electricity to remain stable and continuity, it must be overcome
Solar radiation has a great effect on the output of the photovoltaic system. Wind speed is directly related to the cooling of the PV system and can also affect the performance of the solar collector. This research looks at the influence of temperature and wind on the efficiency of solar panels. From the results of the tests and calculations, it was found that the temperature of the single crystal panel measured on that day was 44°C, and the temperature of the polycrystalline panel was 43°C. The effect of wind speed on the efficiency of the solar module, calculated based on calculations using the linear regression method, shows a correlation level of R = 0.0281. This means that only about 2.81% wind speed will affect it. Has solar module efficiency. From the various aspects of the calculations carried out, we can see that the efficiency of the single crystal panel is 11.716%, while the efficiency of the polycrystalline panel is 10.02%. From the calculation results, we can conclude that the efficiency of the single crystal module is significantly increased.
