A Power System Modeling Framework for Future Power Systems
Abstract:
There are many indications that the future power systems will be more diverse as compared with the ones of today and yesterday. As examples of new types of system components non-dispatchable generators, energy storage, consumers with load management schemes, etc. can be mentioned. Furthermore, it can be assumed that the electric power system will interact more with other energy carrier systems, such as gas and heating systems, and with other infrastructure systems such as transportation systems, e.g. electric vehicles of different types. In order to meet these new modeling demands novel concepts for system-level considerations have been developed, which allows the modeling of technologically diverse unit portfolios with a unified approach. Two types of frameworks are discussed, the energy hub and the power node. These frameworks can be used for designing operational strategies, especially in the presence of non-dispatchable generation and significant storage capacities, as well as for evaluation of operational performance in terms of energy efficiency, reliability, environmental impact, and cost. In the energy hub framework the interaction with other energy carriers can be analyzed and optimized.
