What is a multisource energy storage system?

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.

Why are energy storage systems important?

Abstract: Energy storage systems (ESS) are indispensable building blocks of power systems with a high share of variable renewable energy. As energy-limited resources, ESS should be carefully modeled in uncertainty-aware multistage dispatch.

Should energy-limited resources be modeled in uncertainty-aware multistage dispatch?

As energy-limited resources, ESS should be carefully modeled in uncertainty-aware multistage dispatch. On the modeling side, we develop a two-stage model for ESS that respects the nonanticipativity of multistage dispatch, and implement it into a distributionally robust model predictive control scheme.

What are dispatch optimization problems?

These dispatch optimization problems can either solve the storage system operations in isolation, i.e., the final result is the optimization model solution, or it can be solved iteratively using a performance model to maintain feasibility, i.e., the performance model output is the final solution given a control signal from the dispatch model.

What is an electric thermal energy storage system?

Akin to the latter, electric thermal energy storage (ETES) systems uses a high temperature medium to store thermal energy; however, unlike PTES systems which use a heat pump, ETES systems use electric resistance heating elements to charge the thermal storage medium.

Is the dispatch solution revenue maximizing?

The dispatch solution is revenue-maximizing, and is dependent on the electricity prices and the solar resource available during the problem horizon. Figure 10 shows four days of the operations schedule followed by the SAM simulation, as prescribed by the dispatch solution, for the best-found PV-with-battery plant design shown in Table 8.
