Optimal Distribution Grid Operation Using Demand Response

This paper presents a model in which the distribution system operator can take advantage of the flexibility of end-users to overcome some operation issues on low voltage networks. Distributed generation based on renewable energy sources connected to these kinds of networks is challenging the conventional control and operation framework designed for passive distribution networks. Considering this, the proposed research work presents a non-linear problem using the flexibility available in the end-users to minimize the operation costs of the distribution system operator. For this goal, it is seeking the minimization of power losses and flexibility acquisition costs. The presented case study considers a realistic low voltage network with 256 bus and 96 connected end-users to show the approach effectiveness.
