Optimal Positioning of Distributed Generation Based on its Penetration Using Backward-Forward Sweep Method

Increasing energy demand stresses the grid resulting in low voltage levels. Distributed generation improves voltage levels as well as helps in the integration of renewable energy generation. Although only connecting Distributed Generation without analyzing its impact on the system is not economical. Therefore, analyzing the impact of Distributed Generation in terms of voltage profile and losses is essential. Also, the optimal positioning of Distributed Generation does have a significant impact on the system. Hence a thorough analysis is essential before designing a new electrical system or improvising an existing one. This work analyzes the impact of Distributed Generation in different cases. The analysis is done for Distributed Generation penetration when varied from 10% to 50% of the maximum real power demand. Then the optimal location of a Distributed Generation placement is identified based on the minimum power loss. Later, a case study is presented for IEEE 33 bus system and simulated in MATLAB. The analysis uses solar photovoltaic-based Distributed Generation with a battery as storage.
