“…An output of the RE-SERVE project, which funded this study, is the deployment of an Optimal Power Flow (OPF) (Carpentier 1962) derived method, known as Active Voltage Management (AVM), to edge DER components in an effort to increase voltage stability and reduce energy losses. This method has two stages, the first is off-line modelling of the steady state of the network to determine the optimal voltage using the 3-OPF tool (Bakhtvar et al 2017), producing a Volt-VAr curve (VVC). In the second stage the VVC is deployed to a real-time controller on the RES unit.…”

“…As the electrical power industry shifts from being centralised to a more distributed generation and distribution model, ICT support has become essential. ICT can assist with core operations, billing and demand prediction (Bakhtvar et al 2017). Such applications require (data) network connectivity (typically a dedicated network or a virtual private network over the public internet) between all interconnected devices in the energy network, collectively known as the smart grid.…”

The management of distribution and transmission networks is becoming increasingly complex due to the proliferation of renewables-based distributed energy resources (DER). Existing control systems for DER are based on static specifications from interdependent network connection documents. Such systems are inflexible and their maintenance requires concerted effort between grid stakeholders. In this paper we present a new supplementary control approach to increase the agility of the electricity grid. The ICT system that underlies smart grids has the potential to offer, by analogy with ICT based network management, a control plane overlay for the modern smart grid. Policy-based Network Management (PBNM) is widely deployed in managed telecoms networks. We outline how PBNM can augment the management of power and energy networks and report on our initial work to validate the approach. To configure the PBNM system, we have used text mining to derive connection parameters at the LV level. In our simulations, PBNM was used in collaboration with a Volt-VAr optimisation (VVO) to tune the connection settings at each DER to manage the voltage across all the buses. We argue that the full benefits will be realised when stakeholders focus on agreeing relatively stable high-level connection policies, the policies being refined dynamically, and algorithms such as VVO that set connection parameters so they are consistent with those high-level policies. Thus faults, power quality issues and regulatory infringement can be identified sooner, and power flow can be optimised.
