Abstract

The growth of rooftop photovoltaic (PV) systems in Indonesia has increased rapidly as part of the national effort to develop decentralized renewable energy. PT PLN (Persero) North Makassar Customer Service Unit, with a total of 409,025 customers and an installed capacity of 1,332 MVA, has integrated seven rooftop photovoltaic customers with a total capacity of 419.5 kilowatt peak (kWp). The main challenge of integrating rooftop photovoltaics is the system's ability to channel solar energy while maintaining service and operational standards. This research investigates the impact of rooftop PV penetration on power quality parameters, including voltage fluctuations, harmonics, and distribution system reliability in one of the feeders of the PLN North Makassar area. The Salodong feeder, in particular, consists of 137 transformers with a total capacity of 32.9 MVA, serving customers from various tariff groups, including industry, business, social, and residential. The impact of rooftop photovoltaic penetration on the distribution system is evaluated by analyzing various levels of rooftop photovoltaic penetration. Additionally, this study also proposes strategic recommendations that can be implemented to optimize rooftop photovoltaic penetration. The findings highlight a critical penetration threshold, which, if exceeded, will affect power quality limits and propose mitigation strategies to avoid excessive reverse power, high harmonics, and voltage fluctuations. An optimal rooftop photovoltaic penetration level of approximately 30% is recommended, serving as a reference for the PT PLN (Persero) network planning team to enhance PV integration while maintaining system performance.

Abstract

In recent years, the response to climate change and the need for sustainable energy have driven the global energy transition towards renewable energy, particularly Solar Power Plants (SPP). As a tropical archipelagic country with abundant solar energy potential, Indonesia is increasingly committed to integrating renewable energy into the national electricity system. However, integrating SPP also has several drawbacks to the electrical system. For instance, there is an absence of inertia in SPP because the SPP does not contain rotating machines, and the intermittency is due to SPP power production being highly dependent on the availability of sun irradiance. This research analyzes the effects of SPP penetration on the existing electrical system. Newton Raphson load flow, three-phase line-to-ground short circuit, and transient disturbance are used to investigate the impact of SPP penetration. The results show that the SPP penetration enhances the voltage steady state profile due to the additional active power from SPP. Furthermore, there are no increasing short circuits due to the characteristic of an inverter with no impedance. In addition, the transient response has an effect as SPP has no inertia. Hence, the system tends to experience swings in conditions.
