Modern energy systems are expected to be multi-modal and incorporate electrical, gas and heat networks –so to achieve maximum usage of every form of energy available– and to include storage capacity. The distributed nature of new resources (generation and storage) and the participation of loads in energy management require fast, reactive control and protection. In this context the monitoring and control of modern energy systems are expected to be characterized by distribution of functions. At the same time –to ensure optimal coordination– a large use of communication media is envisioned. Interactions between continuous dynamics and discrete events are becoming more relevant due to the increasing number of controllable devices (e.g. power electronic converters in the electrical grids) and the use of networked control schemes. Energy systems, furthermore, are increasingly driven by market competition. Because of these characteristics –and because of human involvement– modern energy systems can be therefore classified as complex and concerns about emerging behaviors might be raised.The complexity of modern energy systems poses significant challenges on how these systems are planned, designed and operated. Indeed, the projects already supported by the SPP 1984 effectively propose new approaches for analysis, control, modeling and stability assessment of hybrid and multi-modal energy systems. While many of the funded project make use of simulation tools, none of the existing project focus on the development of simulation methodologies targeting multi-modal energy systems. The goal of this project is to study and define methodologies for the effective use of parallel in space and time techniques for the simulation of multi-modal energy systems so to achieve faster than real-time performance. The use of parallel in space and time methodologies seems well fitted for the spatially and temporally distributed nature of multi-modal energy grids.We already demonstrated that with parallel in space methods and Field-Programmable Gate Array (FPGA) execution we could achieve real-time performance (with 100ns time step) also for large energy systems. In the framework of multi-modal energy grids we can expect that -with parallel in space parallelization- we will achieve 10-100X faster than real time performance -assuming that the fastest dynamics of interest are in the millisecond range. This is clearly not sufficient to effectively support analysis and design of multi-modal grids with very long horizon scenario -e.g. one month of simulation time will still require about a working day. We believe that parallel in time methodologies will provide an additional 50-100X time speed up. The two technique combined should ensure an effective use of simulation for the design and analysis of multi-modal grids.
