TEMPO Project - D4.3: Report โ€“ Integrated Improved Innovations In A2A Network

This deliverable describes the innovations installed in the A2A demonstrator as well as the main technical and economic aspects of those implementations, the measures for the implementation quality control, the commissioning of the demo site and initial operation.

The focus of the first version of the ICT platform was to create a functioning platform for data management, including functionality and accessibility for systems and users. The visualization part of the first version focused on the EnergyView platform and on demo site buildings.

The Smart DH controller developed in TEMPO builds further on the STORM-controller. In essence, the STORM-controller is a demand side management system for DHC networks. It makes use of the thermal mass of the buildings connected to the DHC network. The controller is able to achieve 3 different control objectives (i.e. peak shaving, market interaction and cell-balancing). 
Three different control strategies were developed and implemented:

  1. Return temperature minimization: By temporarily reducing the heat demand of connected buildings, it is possible to lower temporarily the return temperature.
  2. Supply temperature optimization: the water in the network pipes itself is used to store heat temporarily.
  3. Combination of supply and return temperature.

Compared to the state of the art, one distinctive feature of the TEMPO innovation was a general investigation of situations leading to high return temperatures and their modelling in coupled building and system simulations. Several improvements were made in version 2 as compared to version 1, including continuous improvements in terms of simulation models, calibration of simulations and adjustments to the practical guide. The main improvements were:

  1. Fault detection and diagnosis with new algorithms and for shorter periods;
  2. Interactive guide for technical audit of building installations in the form of a web page;
  3. Connecting fault predictions with the guide: Having a web version of the guide for technical audit of building installations made it possible to establish a connection between two outcomes of the innovation, which were not yet connected in version 1.
