Running from July2019 to June2021, the project looked at how the DSO will be able to reduce their costs of operation in terms of technical losses, congestion costs, penalty costs to the TSO by efficiently accessing and utilising the flexibilities available from the LV grids. The scientific results achieved are –
•The project demonstrated the importance of LV monitoring for secure and optimal grid operation
•GiFlex was to develop an algorithm to estimate aggregate flexibilities from the LV grid at the secondary substations and at the primary substations with and without forecast uncertainties
•It developed grid aware algorithms for flexibility activation with model-based MV grid and model-less LV grid approaches
•It proposed a solution for fast and slow flexibility services provision to the grid operators
Further, the work also carried out intensive career development activities and two-way transfer of knowledge. The fellow participated in many webinars, meetings and discussions, organised several seminars and workshops, gained knowledge on project management skills, gained a thorough understanding in the host’s product. Some important professional networks were made through participation in project meetings, webinars and conferences. Through the presentation in conferences, seminars and workshops, the valuable skills of effective communication were learnt. The value of LV monitoring is published in CIRED Workshop 2020. The estimation of flexibility at the secondary substation with and without uncertainties is published in CIGRE Symposium 2021; the activation of flexibilities whilst ensuring grid security and minimum technical losses are demonstrated in the conference publication at CIRED 2021. 1 journal publication addressed the problem of optimal operation with MV and LV grids together and estimation of fast and slow flexibility services separately at the TSO interface. The outcomes of the project were disseminated by maintaining a webpage on the host’s website, by organising seminars and workshops for the commercial teams, by participating in an interview organised by the communications team. The findings of the project were discussed or communicated to the commercial team, who are directly facing the stakeholders (DSOs). The scientific value of GiFlex has tremendous potential to be implemented in the GridEye platform and commercialised in future.
