“…When distributed generation is added to the extremities of the distribution network, a change to the voltage profile along the conductor carrying the current (commonly called a feeder in distribution networks) can limit the amount of power that can be transferred by the network. Solutions have been implemented that modify the automatic voltage control (AVC) settings at the primary substation to increase the sophistication of voltage management across all the feeders on the network such as Fundamentals SuperTAPP n+ and Senergy Econnects GenAVC (Fila et al, 2008). Energy storage has the potential to achieve a less invasive intervention, largely acting on only a single feeder, as has been explored by several authors (Arulampalam et al, 2006) (Barton and Infield, 2004) (Tande, 2000).…”

AbstractInterest in electrical energy storage systems is increasing as the opportunities for their application become more compelling in an industry with a back-drop of ageing assets, increasing distributed generation and a desire to transform networks into Smart Grids. A field trial of an energy storage system designed and built by ABB is taking place on a section of 11kV distribution network operated by EDF Energy Networks in Great Britain. This paper reports on the findings from simulation software developed at Durham University that evaluates the benefits brought by operating an energy storage system in response to multiple events on multiple networks. The tool manages the allocation of a finite energy resource to achieve the most beneficial shared operation across two adjacent areas of distribution network. Simulations account for the key energy storage system parameters of capacity and power rating. Results for events requiring voltage control and power flow management show how the choice of operating strategy influences the benefits achieved. The wider implications of these results are discussed to provide an assessment of the role of electrical energy storage systems in future Smart Grids.

“…This can be based on local measurements at the substation and also at the DG combined with state estimation techniques to assess voltage rise at the point of connection of DG and adjust the substation voltage accordingly. It involves relatively simple installation techniques and configuration protocols however it is susceptible to uncertainty in the state estimation techniques [14].…”

With the uptake of embedded renewable generation on distribution networks, it is becoming increasingly challenging to maintain the network within thermal and voltage limits. The application of Active Network Management (ANM) to provide additional thermal and voltage capacity headroom has been successfully applied to connecting wind farms in recent years. Analysis was undertaken in this study to explore the extension of ANM application to solar PV plants including both the technical and the commercial implications. A real power curtailment scenario was developed and applied to a 33kV distribution network located in the South West region of the UK with a number of solar PV plants already connected and accepted to connect. Power systems network modelling was carried out that integrates a Last In First Out (LIFO) algorithm to assess the representative levels of curtailment over a typicalyear. The results indicate that by applying an ANM technique to the network, the connection of an additional 22MW of PV (35% increase on the installed capacity) was achieved while curtailing the annual generation output of the additional plants by 12% only. A high level commercial assessment suggests that the deployment of ANM for PV plants generates substantial net benefits compared to a traditional network reinforcement approach.

“…Considering the above figures for PV, storage and electrification, at least two critical scenarios emerge: the traditional peak load scenario and the peak generation or low demand scenario [12]. Arguably, the single case ADMD based design approach can be easily extended to include a second scenario.…”

This paper examines how Australian residential load profiles may evolve in the short to medium term future. These profiles can be used to support simulation studies of the future Australian network within an environment that is transitioning to renewable energy and broader use of electricity as a tool for decarbonisation. The daily profiles rely heavily on the Australian Energy Market Operator (AEMO) forecasts for future annual energy usage. The period from 2024 to 2050 will be transformational. In the residential networks, two secular trends are particularly important in expanding residential generation and electrification. New daily load profiles have been constructed using historical Australian profiles and adding additional components for solar generation, battery operation and electrification activities. The entire aggregated residential network is expected to have reverse midday power flow on any average day from 2024 onwards due to the rapid increase in electric vehicle (EV) usage. The domestic energy demand forecasting methodology presented in this work related to Australia can easily be adopted to carry out similar forecasting for any country of the world.
