Integration of distributed generators (DGs) using cooperative game theory (GT) at IEEE 33 bus system and 69 bus Ramchandrapura, Kota, India radial distribution feeder. GT is operated on multiple variables (i.e., voltage indexing, phase angle, real power losses, and reactive power losses, etc.) with communication or cooperation with another consumer. DG integration is challenging due to random character of generation, energy consumption, and losses associated with particular bus. The objective of this research is to minimize the voltage drop by improving the voltage indexing and reduce the power losses by identifying the size and location to connect DGs on standard IEEE 33 bus system and 69 bus Ramchandrapura, Kota feeder. Forward/backward sweep methodology is used for load flow analysis. A centralized DG is connected at all nodes on the radial distribution network will increase active and reactive power losses. DGs placement are essential for voltage profile management and active and reactive power loss reduction. Cooperative GT is applied on the connected buses through integration of DGs on multiple variables. Voltage profile and impedance of DG lines are the two variables that are taken into consideration. The focus of this research is to select the bus having least voltage profile and least losses for connecting DGs based on predefined rules.
