Abstract: A multisource energy storage system (MESS) among electricity, hydrogen and heat networks from the energy storage operator's prospect is proposed in this article. First, the framework and device model of MESS is established. On this basis, a multiobjective optimal dispatch strategy of MESS is proposed.
Table 1. Summary of dispatch approaches for energy storage in power system operations. Extended optimization horizon or window of foresight: extend the optimization horizon to consider more than one day at time or add additional foresight (look-ahead window). Straightforward implementation and consistent with current market settings.
The multi-energy system depicted in Fig. 4 comprises a 6-node electricity network, a 7-node HCNG network, and a 10-node DHN. Within the electricity network, the power grid, wind turbines, and CHP units serve as the primary energy sources to fulfill the energy requirements of 3 electricity loads.
A better storage dispatch approach could reduce production costs by 4 %–14 %. Energy storage technologies, including short-duration, long-duration, and seasonal storage, are seen as technologies that can facilitate the integration of larger shares of variable renewable energy, such as wind and solar photovoltaics, in power systems.
The flexibility of multi-energy systems is quantified considering dynamic pipelines. Day-ahead scheduling is optimized for a balance between efficiency and flexibility. A data-driven real-time dispatch optimization method is proposed based on DDPG. Two-stage dispatch strategy is modified for renewable energy accommodation.
The exogenous dispatch model may not accurately represent the optimal operation of energy storage technologies due to necessary simplifications in dispatch model. Stored Energy Value: use the marginal future value of storing an additional unit of energy (usually in $/MWh) to operate the storage devices.
