Customer ServiceA methodology was proposed to maximize the photovoltaic hosting capacity of low-voltage distribution systems through the reduction in the number of probabilistic scenarios which violate the voltage operational constraints of the system.
Based on the results achieved for the system with 30% and 70% of customers with PV installed, it is noted that this variable significantly influences the hosting capacity of the system, which highlights the importance of carrying out an individual analysis for each case.
The maximum amount of PV generation that an existing distribution system can accommodate without violating operational limits while ensuring system stability is referred to as the PV hosting capacity , , , . There are many methodologies used to quantify the HC of distribution systems.
Smart inverters with differing Volt-VAr and Volt-Watt control functions are modelled in the DIgSILENT PowerFactory platform. Influence of different connection standards on solar photovoltaic hosting capacity is analysed to investigate the most beneficial connection approach/es to address the issue of voltage violations.
Control strategies: Volt-VAr, Volt-Watt and combined Volt-VAr & Volt-Watt were assessed. Combined Volt-VAr & Volt-Watt control is effective in enhancing hosting capacity. Hawaii Rule 14 and IEEE 1547 are effective to increase solar PV hosting capacity. Volt-VAr control is the most effective with bare conductors.
Feeder segments where Volt-VAr and Volt-Watt control modes are effective. Table 5. Maximum solar PV hosting capacity enhancement at feeder end. In general, the increase of voltage constraint limit from 1.06 p.u. to 1.1 p.u., facilitates significant enhancement of HC for both control strategies.
