The energy transition will abruptly increase the renewable energy supply and electric load demand. Electrification of heating with heat pumps (HPs) and of the transportation sector with electric vehicles (EVs), as well as higher distributed generation (e.g PVs) will play an essential role in energy transition success.
High uncontrolled penetrations of EVs, HPs and PVs (low-carbon technologies LCTs) can provoke several grid impact issues, such as transformers and lines over-loading and severe node voltage deviations. On the contrary, utilizing their flexibility with energy storage systems (ESSs) within a coordinated control system can minimize their grid impact and needed grid investments, increase cost savings and penetration level. Moreover, ancillary services can be provided to the system operation (SO), such as frequency regulation, congestion management, etc. The first part of this Ph.D. dissertation aims to identify and quantify the future grid impact of the high uncontrolled penetrations of the LCTs above and motivates the rest of the research. In the second part, a grid-level coordinated control is developed, which intends to optimize the grid operation in terms of power dispatch, ancillary services provision to the SO, energy storage utilization and component degradation.
