Using advanced modular FACTS to increase flexibility of distribution networks and enable the connection of more distributed energy resources

UK Power Networks undertook the “Loadshare” project – an implementation of modular FACTS on the UK distribution network. This installation utilizes novel technology and a load-balancing algorithm to optimize loading on three parallel circuits and maximize network transfer capacity in real-time. It resolves network constraints, allows new DERs to connect and maximizes use of existing network without the need to pursue costly, time-intensive and disruptive system reinforcements.

Planning of anefficient power system with the use of modular staticsynchronous series compensation to enable flexible operational services

This paper outlines the increasingly changing network issues that arise in a distribution network and the ability of MSSSC’s to mitigate these issues. The paper will show how a deployment of MSSSC’s can enable the efficient use of providers of flexibility services like storage or electric vehicles. The paper will also show how MSSSC’s can be repurposed from ampacity issues, to voltage and transient stability issues through to harmonic, phase balancing and temporary overvoltage issues in support of delivering these flexibility services. Supporting cost benefit analysis in the paper will evaluate the cost effectiveness of this modular power flow deployment approach and the value fromthe resulting flexibility services.
