Optimal Operation of Distribution System Using Network Reconfiguration in Presence of Different Energy Resources

To improve the distribution network’s (DN) performance, radial distribution reconfiguration is an emerging viable solution. Manual techniques or automatic switching operation techniques are used for varying the network configuration. The purpose of reconfiguration of DN is improving the voltage profile and to minimize the losses. This paper represents a model network reconfiguration for radial distribution system with renewable DGs. The model proposed here aims to minimize the operating cost and deviation in voltage. Different constraints are considered such as power balance constraints, network security constraints, and energy resources constraints. The model proposed is being tested by considering the 33-bus distribution system with the consideration of different types of renewable energy sources. The proposed model is implemented in General Algebraic Modeling System (GAMS). The efficiency of proposed model is established, and a comparison of results between base case and tested system is presented where the model attains improving voltage profile and cost minimization of DS. The proposed model in which both network reconfiguration and energy resources are considered shows an effective result in enhancing voltage profile as well as loss minimization with the inclusion of voltage and angle constraints, power balance constraints, and energy resources constraints, the total cost of operation is also reduced, GAMS with CONOPT solver is used for cost optimization, the base case and proposed model case results are compared, and the later one is found to be very effective.
