Abstract:
In this thesis integration of price responsive demands and controllable loads in operation of unbalanced the phase's smart distribution networks is investigated. To this end, the optimal power flow formulation of unbalanced three phase's distribution networks is presented and then the linear and exponential models of price responsive demands are developed. Moreover, a new model is proposed for controllable loads. In the proposed model, by receiving price signals from operator the controllable loads adjust their consumptions during scheduling period while their energy demand is constant. The objective functions are presented in the point wives of consumers and operators of distribution network which include minimization of energy purchasing, loss and customers' bill. Moreover, the peak load constraint of distribution network is considered.
Regarding the two objectives in the proposed model, optimization is utilized to solve the proposed model. The operator could select one of obtained solutions according to his policy. Moreover, to consider the uncertainties of demand response parameters, a Monte Carlo simulation approach is developed. To this end, uniform probability distribution functions are assumed and efficient samples are generated during scheduling period and then the optimization is solved.
The proposed model is simulated on the modified 13 buses IEEE distribution network. The obtained results illustrates integration of demand response in the operation of distribution network leads to flatted load profile and therefore lower peak load, lower energy demand and loss and therefore simultaneously lower cost for the operator and consumers.
Keywords: Demand response, operation, optimization, unbalanced three phase's distribution network, smart distribution network.
