Optimum distribution network operation considering distributed generation mode of operations and safety margin

摘要

This study analyse the impact of different distributed generation (DG) operating modes towards the system performance when network reconfiguration, DG generation and tap changer setting are simultaneously configure to optimal value. The main consideration in the optimal configuration process is to minimise daily power losses. For the purpose of optimisation, imperialist competitive algorithm is applied. Analysis is conducted based on safety margin of total DGs penetration, photovoltaic generation based on daily irradiance and daily load profile. The analysis of different DG mode of operations is conducted using IEEE 33 having five tie-switches and one on-load tap changer.
