CIRED 2012 Workshop: Integration of Renewables into the Distribution Grid, 2012

Electrical Energy Storage (EES) systems can play an essential role in facilitating renewable energy integration by mitigating voltage rise problems and unbalanced issues. As part of the Customer Led Network Revolution (CLNR) smart grid project, this paper describes research relating to the voltage rise issues arising from large-scale PV integration and presents a solution using EES, based on data analysis from a field trial network, PSCAD simulation and laboratory emulation.

This anticipated growth offers significant environmental benefits but also technical issues regarding network integration and operation. Current EPSRCfunded research in The New and Renewable Energy Group at Durham University seeks to address these issues. Since Small-Scale Embedded Generators (SSEGs) are likely to use single-phase connections, voltage unbalance has the potential to become a serious concern for Distribution Network Operators. Voltage unbalance in distribution networks is undesirable as it can cause problems for three phase load equipment and generators. This paper presents a dynamic model that is used to investigate the degree to which SSEG contributes to voltage unbalance in a generic LV network. The model is based on the IEC Technical Report 60725 and on data approved by work stream 3 of the DTI / Ofgem Technical Steering Group (TSG).

This work has been carried out as part of the Customer Led Network Revolution (CLNR) project which is funded by Ofgem's Low Carbon Networks Fund. Modelling and simulation work is presented, which demonstrates the operation of the control system. Field trials will be carried out in 2012, to implement and evaluate the control systems on the case study network.

Distribution networks are not a homogenous group with more capabilities to accommodate EVs than previously suggested. Spatial and temporal diversity of EV charging demand alleviate the impacts on networks. An extensive recharging infrastructure could enable connection of additional EVs on constrained distribution networks. Electric utilities could increase the network capability to accommodate EVs by investing in recharging infrastructure.

He spared a lot of time from his hectic schedule to explain the physics of the experiments we performed and thus gave us a solid theoretical ...
