Coordinated local reactive power control in smart distribution grids for voltage regulation using sensitivity method to maximize active power

الملخص EN

Distributed generation (DG) integrated into Smart grid is the future of distribution systems. The expected impact is wide in terms of control, management, supply and use.

In particular, in order to integrate DG based on renewable sources in distribution networks without compromising the integrity of the grid, it needs to develop proper control techniques to allow power delivery to customers in compliance with power quality and reliability standards.

This paper proposes a coordinate local control approach based on a mixed distribution network (DN) sensitivity analysis to maintain voltage levels within regulatory limits.

The proposed control is based on a reactive / active power regulation able to offer voltage regulation as ancillary services to the DN, and to maximize the produced active power of the DGs.

The validation of the proposed control technique has been conducted through a several number of simulations on a real MV Italian distribution system.
