Optimal planning of wind-based distributed generation and reactive power management in a distribution system

In recent years, the incremental load demand leads to the higher presence of distributed generation (DG) in distribution system. Renewable energy-based DG has been much appreciated due to the techno-eco-environmental benefit. Wind-based DG is one of most promising renewable energy based-DG. However, in the technical aspect, distribution system planning with wind-based DG alone is not fruitful enough due to limited reactive power support. Capacitor bank is one of available devices for reactive power management in distribution system. So, installing wind-based DG and capacitor bank in distribution system is one of alternative solutions to improve electrical power system performance in term of voltage profile and power loss. However, to achieve techno-eco-environmental benefit, an appropriate place and a suitable size of wind-based DG and capacitor bank requires to be determined optimally. This study proposes a model to determine an optimal placement and sizing of wind-based DG and capacitor bank in distribution system. The planning model is managed considering techno-eco-environmental benefit such as voltage profile improvement, power loss reduction, carbon-di-oxide emission mitigation, and annualized cost of system (ACS) minimization. Wind speed uncertainty is also considered to define the number of wind-based DG requires to be installed in distribution system. The effectiveness of proposed model is verified in 33-bus IEEE test system using MATLAB R2018b.
