Study on Photovoltaic Hosting in Yogyakarta Electric Distribution Network

摘要

The development of power generation technology enables the location of the plant which is no longer centralized but becomes scattered in several distribution channel locations close to the load. The interconnection of PV into the distribution network may result in potential disruption of operating conditions and result in problems in power quality. The hosting capacity is defined as the number of new production or consumption that can be interconnected with the network without any adverse impact on the reliability or quality of the voltage on the consumer. The hosting capacity also ensures that there are no broken parameters, i.e., the current carrying capacity distribution network and power flow direction. An iteration approach with voltage constraints, power flow, and current conductivity capability is used to determine the amount of PV power capacity that can be injected into the network. The impact of PV interconnection into the network, especially the voltage and power flow is studied to determine the capacity of PV hosting. The results show that the PV hosting capacity of the distribution network in Yogyakarta through GI Kentungan is equal to the current load on the distribution network.
