Strategic Technology Programme

STP Module 5 =

The Strategic Technology Programme (STP) provides research, development and technology to Electricity Distribution Network Operators (DNOs) in the UK and Ireland

what is distributed generation
What is “Distributed Generation”?
  • All generation connected to an electricity distribution network (up to 132kV) potentially selling surplus electricity back into the network, including:

– Small-scale plant that supplies electricity to a building, industrial site or community

– Microgeneration, ie small installations of solar panels, wind turbines or biomass/waste burners that supply one building or small community

  • Combined Heat and Power (CHP) plant, including:

– Building or community level CHP plant

– Micro-CHP plant that effectively replaces domestic boilers, generating both electricity and heat for the home

Module 5 – 2006/07

Module Title

“Networks for Distributed Energy Resources”

Addition to Module Scope

Moving to lower carbon network designs and the development and operation of distributed resources, the following are within scope:

  • Network design, distributed generation, demand-side management, storage and active network management
  • Implications for distribution networks of the Government’s low-carbon strategy

Approved in January 2006

module 5 objectives
Module 5 Objectives
  • To facilitate increased understanding between all participants on technical and commercial and regulatory issues and develop effective solutions to these issues
  • To ensure that all participants optimise networkdesign, financial and operational performance as the levels of storage, managed-demand and distributed generation increase on the distribution networks
  • To maximise the opportunities to the module participants arising from active network management and low-carbon networks, with regard to network reinforcement and network security
  • To reduce the costs associated with network connection

DG = Distributed generation

DNO = Distribution Network Operator

Planned dates for large multi-stage projects:

S5147 “Microgenerator clusters” Feb 2006 - April 2008

S5149 “Active voltage control” Jan 2006 - July 2008

s5147 micro generator clusters
S5147 Micro-generator Clusters
  • S5140 Domestic Combined Heat & Power Potential (Sep2004) concluded that short term impact of dCHP on a national scale will be small - but clusters of dCHP units (e.g. a whole new build housing estate) could have significant impact locally (e.g. networks coping with new situations such as reverse power flow)
  • Lovell Homes are building ~500 homes on a brown field site in Manchester. All houses will have 1kW WhisperGen CHP units supplied by Powergen
  • S5147 is a more complete study of the effects of dCHP clusters on load and voltage profiles providing real measured data for low voltage network design with microgeneration - to be written into a national

Engineering Recommendation

S5149 Active Voltage Control

The objectives of the project are:

  • To understand the technical and commercial advantages and disadvantages of voltage control equipment when connecting different types of DG
  • To understand how different types of DG and AVRs can aid voltage profile on an electricity distribution network

DG = Distributed Generation

AVR = Automatic Voltage Regulator
