Summary
Distributed generation (DG) technologies are considered an integral part of power distribution networks. The desired performance of power distribution networks can be obtained through the optimal accommodation of DG units. This paper proposes an analytical method called Branch Loss Bus Injection Index (BLBII) to solve the multi‐objective optimal accommodation of distributed generation (MO‐OADG) problem of power distribution networks. Four objectives were considered in the optimisation model: energy loss minimisation, overall bus voltage deviation minimisation, overall voltage stability margin maximisation, and energy not served (ENS) minimisation. A multiple criteria decision‐making method such as the analytical hierarchy process is employed to optimise the weight coefficients of the individual objectives as the optimisation problem is solved based on the weighted‐sum method. The proposed method is demonstrated on benchmark radial power distribution networks of IEEE 33‐bus and INDIAN 85‐bus. The applicability of the proposed BLBII has been validated, and results are presented.
