While these changes might save on your monthly bills\, they also have pr ofound effects on our power systems. Electric vehicles\, PVs\, heat pumps\ , and other elements collectively form what we term as distributed energy resources (DER). But is the surge in DER integration a boon or bane for th e power network? The answer is: both. Without strategic integration\, DERs can lead to excessive consumption or generation\, resulting in network co ngestion. However\, when DERs are controlled and coordinated\, they can en hance the system's flexibility. From a market standpoint\, DERs supply fle xibility services\, and the distribution system operator (DSO) compensates for this service to mitigate congestion.\n\nThis research aims to aid the DSO in navigating challenges related to network congestion. The work delv es into estimating the network state for nodes lacking measurements\, pinp ointing available system flexibility\, and evaluating the impacts of flexi bility services on network states. The study not only enhances estimation accuracy in networks with limited observability but also introduces a nove l tool for DSOs to identify system flexibility at the substation level. Ad ditionally\, the research formulates a framework to understand the effects of capacity limitation services. The interaction between DER and DSO is p ivotal\, especially when the efficacy of flexibility services is occasiona lly constrained by DER availability or capacity\, failing to meet DSO's ex pectations.\n\nWith the rising wave of digitization and DER integration\, this research explores the ingenious utilization of DER to maintain power system security within the energy sector. Backed by real-world datasets an d industrial network models\, simulation results authenticate the findings .\n\nThe presented thesis is intended for both academic and industry audie nces. Academics can derive insights from the cross-disciplinary literature analysis and the practical application of power system modeling analysis.
