Pbkp_redictability and Voltage Profile Improvement of Distribution Networks with a D-STATCOM Model

Abstract:

This paper presents a modeling for D-STATCOM device into Monte Carlo probabilistic load flow algorithm. The model is used to improve the pbkp_redictability and voltage profile of distribution networks. In this model, the D-STATCOM’s bus is represented as a special generator bus which injects reactive power only. The injected reactive power of D-STATCOM is updated during the iterative process to maintain the voltage magnitude at the specified value. The model can be easily implemented in the original PLF code without deeply modifications. The probabilistic load flow (PLF) with D-STATCOM model is validated using various standard IEEE tests systems; 33-bus, and 69-bus systems. The PLF algorithm with DSTATCOM model has been evaluated based on MATLAB package. However, the obtained results prove the effectiveness of D-STATCOM implementation in the test systems regarding to pbkp_redictability and voltage profile issues. Moreover, the standard deviation of the systems is decreased.
