Short description

The main purpose of this HLUC is to describe how multi-vector local generation, on-site multi-vector storage and Building Management Systems (BMS) should interface with an Energy Management System (EMS) of a Local Energy System (LES) enabling optimized operation, through the integration of advanced functionalities provided by the E-LAND Toolbox.

Optimal operation of a LES encompassing multi-vector DER generators (thermal or electrical); on-site multi-vector storage (i.e. electrical batteries, hot water tanks, hydrogen storage, building enthalpy) and load priority control facilitated by the BMS could achieve higher efficiency levels than traditional solutions. The integration with advanced tools e.g. forecasting, optimisation as well as to external sources of data (e.g. weather forecasts) - through an Enterprise Service Bus (ESB) - should provide enough information and endpoints for proper EMS automation scenarios to be enforced having as a goal the optimal operation of the Local Energy System (LES). Therefore, the integrations of various field equipment (e.g. storage controllers, DER controllers, actuators, sensors) and the BMS is crucial for the realization of these advanced operations.

Optimal operation of a Local energy system (LES) can be considered from different perspectives (Facility Operator, Microgrid Operator, Aggregator, DER Owner) and therefore achieved by prioritising and/or optimising indices like: energy efficiency, cost of operation, cost of ownership, energy cost, carbon footprint.

Complete description

Traditionally, Energy Management System (EMS) solutions provide a comprehensive way of understanding energy profiles, identifying actual energy use and waste, as well as perform control actions on a variety of production and storage assets of multiple vectors (thermal, electrical, gas).

However, in the case of a Local Energy System (LES) where multiple business actors with different roles exist (e.g. DER Owner/Producer, Consumer), an enhanced solution is required to provide a top-level view of the operation of the system, enabling the realisation of optimisation scenarios. On this basis, the integration of the EMS with the controllers of the various storage and production assets is necessary. On the other hand, the integration with Building Management Systems (BMS) allows a more in-depth knowledge of the facilities’ loads (electrical or thermal), taking priority based decisions and enabling fine grained Demand Response (DR) actions.

On top of that, the EMS can make use of advanced tools related to forecasting and optimal operational scheduling/ future planning, which combined with all the above can help achieve optimal utilization of the constrained grid capacities, maximizing the use of on-site RES, by utilizing multi-vector energy blending, storage and DR actions.

Such an integrated system can enable the operation of the LES with the following advanced features: • Coordinated DER operation • Control over the energy mix and optimal use of storage with energy forecasting • Increased system reliability and power quality • Optimal load prioritization and shifting • Microgrid enabled operations: the ability of all integrated systems to work together as a single system, enabling facilities to operate as autonomous microgrids; • Quantification and measurement of overall carbon foot-print • Detailed monitoring of real-time energy-related data • Alerts for optimizing operational expenditures (OpEx)

The enhanced EMS will encompass the integration of the following sub-systems: • EMS: integrating the traditional DER Owner energy monitoring and control solution; • DER Controllers: On-site devices offering monitoring & control of the production assets of DER Owners; • Storage Controllers (Thermal/Electric/H2) Devices for multi-vector storage management, handling information on capacity and availability of storage assets of DER Owners; • BMS: Offering a monitoring network at a building level (evaluate energy usage/needs, occupancy, production, weather, etc.) as well as assisting real-time, data-driven decisions for the optimization of the consumption, by analysing offering various modes of operation (demand response, store energy) for various vectors; • Field Devices: For sensing or actuation of various loads, integrated through the BMS or directly; • EV/FCEV Chargers: Devices enabling the monitoring and control of the charging of Electric Vehicles and Fuel Cell Electric Vehicles in the LES, typically owned by the local stakeholders or even third parties • External Data Sources: for weather forecasting and energy prices • Advanced tools: for energy forecasting (Energy Forecaster) and for optimal scheduling (Optimal Scheduler) and planning • Enterprise Service Bus (ESB): A system enabling the integration of the above sub-systems
