Short description

The goal of this HLUC is to describe how optimal multi-vector operation of a LES can be achieved, by coordinating the different available assets; providing a solution to the optimal control problem of DER, flexible loads and different storage technologies. On the basis of these flexibility assets and considering the different energy networks (i.e. electricity, heat, gas, Hydrogen) the operator of the LES, aims to achieve specific goals related to the economic operation, reduce environmental impact and reduce the dependency from the main grid. The role of the LES operator can be undertaken by various actors such as: the Distribution System Operator (DSO), the Aggregator (e.g. Virtual Power Plant, EV Charging Infrastructure Owner/Operators), the Microgrid Operator, the Facility Operator; whilst the role of the flexibility provider can be handled by DER Owners i.e. the owners of generation and storage assets of various energy vectors – as well as Consumers and in general an aggregated scheme of the previous e.g. a Community within the LES.

Complete description

The task of leveraging the multi-vector assets of a Local Energy System (LES) for achieving an optimized operation can be viewed by different perspectives. From the perspective of the operator of the grid, pursuing efficiency, reduce environmental impact and reliability; a task undertaken by an actor such as the Grid/Microgrid/Facility Operator. On the other hand, the optimal management of such resources can be leveraged by an Aggregator aiming to maximize its profits through market participation (VPP concept).

The assets involved in a multi-vector LES case concern various type of DERs (e.g. wind, PV, solar thermal), flexible loads (e.g. EVs, FCEVs, HVAC) and different storage technologies (i.e. electrical, thermal, H2). The (multi-vector) flexibility assets are assumed to be provided by the various DER owners and consumers, owned by individuals or the community within the LES. The flexibility providers procure services to the operator of the LES, in order to support the grid operation, improve the overall system efficiency and/or reduce the carbon emissions and are assumed to receive reimbursements respectively. The core functionalities of the optimal operation concern: • Demand side management and the shifting/scheduling of multi-vector loads (see PUC 2 Shift Building Loads using Demand Side Management, PUC 3 Shift Harbour Loads using Demand Side Management) • Optimal scheduling of different storage vectors: electric, thermal and hydrogen-based (see PUC 4 Optimal Scheduling of Thermal and Electrical Storage, PUC 5 Optimal Scheduling of Electrical Storage and Hydrogen Storage, PUC 6 Storing Excess Generation in Thermal Network ) • Optimal Management of EV/FCEV related operations: (see PUC 7 Optimal Management of EV with Hydrogen and/or Electricity) The above functionalities are facilitated by forecasting, scheduling and integration services provided by the relevant tools developed in the project.
