**3. Results and outlook**

The project is at a beginning state, and this means that the consortium is actually working on the elaboration of the potential business cases for the deployment of energy conversion/storage technologies in the European grids, on the investigation of necessary business roles for the successful proliferation of technologies and in identification of PLANET system requirements as an initial step for implementation.

The successful deployment of the global and local level coordination system for power-to-heat and power-to-gas resources depends on seamless information exchange between all actors. This task aims to define the requirements for effective communication and grid interfaces throughout the various system architecture layers to ensure that all necessary information is properly collected and transmitted.

The functional behaviour of the entire system will be finalised and decomposed into the component/module functionalities. Detailed functional decomposition and sequence diagrams will be developed to ensure full interoperability between components. Information exchange and interfaces among (and within functionalities of) components/modules as well as to the outside world will be defined.

Another purpose is to set the requirements and targets that power-to-gas/heat systems should meet so that their decentralised deployment becomes a viable value and business proposition in the future energy systems is fulfilled. PLANET will utilise controllable conversion/storage as flexibility sources for grid balance and stability. To simulate and validate this claim, models of uncontrollable source of electricity demand and supply must be developed as well as projections of heat, gas demand and supply. This to produce the necessary models for energy supply—including conventional generation and variable RES—and uncontrollable demand forecasting in the future energy system scenarios.
