Decentralized control of distributed energy resources in electric distribution grid

The high penetration of Distributed Energy Resources (DERs) in the distribution network has become an inevitable trend, bringing new challenges to the modelling, analysis and control of the grid due to DER's intermittent availability and varied operational strategies. Therefore, in order to ach...

Decentralized control of distributed energy resources in electric distribution grid
description The high penetration of Distributed Energy Resources (DERs) in the distribution network has become an inevitable trend, bringing new challenges to the modelling, analysis and control of the grid due to DER's intermittent availability and varied operational strategies. Therefore, in order to achieve stable operation of distribution networks, it has become necessary to establish appropriate steady-state models of DERs and apply effective control strategies. In this dissertation, an equivalent model of the distribution grid with multiple DERs in discrete-time phasor mode has been developed, along with model of building and its demand profiles, as well as irradiance profile of solar energy. The DERs established include Photovoltaic System (PVS), Battery Energy Storage System (BESS), Electric Vehicle Charging System (EVCS) with Non-Smart Charging (V0G),Smart Charging (V1G) and Vehicle-to-Grid (V2G). Meanwhile, decentralised control enables the output power of the DERs to be controlled in accordance with the local electrical measurements. By eliminating the need for a control centre to coordinate multiple control units, the reliability of the control strategy is considerably increased. This dissertation documents the modelling of DERs and the design of the decentralized control schemes for these DERs. The decentralized control of DERs are simulated in Matlab/Simulink. Simulation results are presented which demonstrate the voltage regulation ability of the local controllers to increase grid stability.
