On-Grid PV, Distribution Network, Voltage Stability, Power Losses, Mini-hydro power plantsAbstract
This study rigorously investigates the effects of PV (photovoltaic) placement on the voltage profile and power losses in a grid-connected micro-hydro power system in West Sumatra, Indonesia. The primary objective is to identify optimal PV installation locations that minimize grid power losses while enhancing voltage stability in a 20 kV distribution network. Through comprehensive simulations, the study assesses the different effects of PV placement at different nodes in the network. The findings reveal that PV integration impacts voltage profiles and power losses differently across the network, with some locations showing improved voltage quality and others exhibiting voltage instability, which can lead to operational challenges. Notably, higher PV penetration is associated with increased grid power losses, reaching up to -9,9 % in certain configurations. These results underscore the need for advanced adaptive power control strategies, such as smart inverters and energy storage solutions, to maintain grid reliability. This study offers actionable insights for grid operators and policymakers aiming to balance the benefits of renewable energy integration with the technical requirements for stable and efficient power distribution.
