Increased adoption of decentralized, variable renewable energy generators will require improved and up-dated methods for managing the increasingly complex energy balancing procedures in future networks. One way to aid in accomplishing this is by exploiting demand side management opportunities available from operating flexibilities and storages available in micro grids. This research aims to quantify and visualize the maximum potential deviations in grid experienced power flows, referred to as flexibility corridors found in residential micro gird systems which could be accessible for use by grid services. To achieve this, a model is developed through sets of mixed integer linear programming formulations, representing a residential PV-CHP micro grid with thermal and electric storages. An energy management system is operated using a rolling horizon optimization approach. Flexibilities are then evaluated based on the predicted state of certain critical components in the system. The system is then resimulated reflecting scenarios in which grid operators signal systems to exploit the entirety of both positive and negative flexibility options. Reactions to the system after such events are then analysed and cost modifications in the altered system operations are determined.
