In this report, the developed model for a multi-energy systems monitoring, control and management is provided. The flexibility of distribution grid is described as the capability of distribution grid to effectively cope with multiple uncertainties of grid operation and presented in the report. The proposed flexibility estimation methodology takes into account the feasible grid operation region and the uncertain region of load and photovoltaic powers. The main results included in the report are:
- The MNRG ensures the optimal operation with reduced losses and operation costs compared to situations where there is no optimality.
- Non-convex feasible operation region in different types of CHP units is formulated as a mixed integer linear formulation in the scheduling problem of multi-energy systems.
- The model can detect other factors like voltage limit violation regarding the grid constraints that limit the grid’s flexibility.
- The outcome of proposed model informs the grid operator regarding the time slots with sufficient and insufficient flexibility along with the value of insufficiency considering the uncertainty space.
-The simulation results for the cases considering and neglecting the reconfiguration ability of the grid confirms the improvement of grid flexibility after reconfiguration.
- The proposed model for the reconfiguration and also power flow is a linear and convex mathematical problem that can be solved efficiently with non-commercial solvers and the optimality of the solution is guaranteed.
During the action, the ER had undertaken several measures to communicate, disseminate and exploit the results. She had organized and talked about the findings of MNRG to a varied audience, ranging from the R&D team to commercial and sales team. The ER had organized several workshops within DEPsys and participated in several discussions with the R&D and engineering teams:
[S1]All about flexibility, Feb 2022, DEPsys commercial team
[S2]Feedback on CIRED 2022, Jun 2022, DEPsys R&D and engineering team
[S3]Flexibility and reconfiguration: Possible roles of DEPsys and GridEye, AUG 2022, DEPsys senior and middle management
