Low Carbon Generation
The proposed project will form the first building block required to answer the following two questions.
- How can voltages at 400kV & 275 kV be kept within statutory limits?
- What factors and trends are there that could be making transmission voltage control increasingly more problematic and/or costly under low load conditions and how do these influence reactive power?
In addition, it will crucially allow DNOs to understand the technical aspects to be tackled in order to comply with the European Demand Connection Code that will in a few years limit GSP exchanges to 0MVAr for load up to 25% of the GSP capacity.
The project will develop key learning relating to the interaction between active and reactive power demand while establishing an understanding of why reactive power is reducing across the country.
