Dispatching rules for energy storage systems

Abstract—The dynamic dispatch (DD) of battery energy storage systems (BESSs) in microgrids integrated with volatile energy resources is essentially a multiperiod stochastic optimization problem (MSOP). Because the life span of a BESS is significantly affected by its charging and discharging behaviors.

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. On the modeling side, we develop a two-stage model for ESS that respects the nonanticipativity of multistage .

The development of renewables and the prevalence of energy storage systems (ESSs) with costly degradation calls for combining the advantages of heuristics and proactive methods in AGC dispatch. With this in mind, a hierarchical AGC dispatch method is proposed.

In the study of optimal dispatching of energy storage, the integrated energy system is modeled according to the energy transmission characteristics of the integrated energy system, which mainly includes the combined cooling, heating and power system and the multi-type energy storage system containing electricity and heat storage.

This study explores the value propositions of operating an energy storage system (ESS) under each application individually, as well as together, in stacked applications through simulations using market pricing data obtained from the California Independent System Operator.

5 FAQs about [Dispatching rules for energy storage systems]

Is dynamic dispatch a multiperiod stochastic optimization problem?

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.

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.

Does the dispatching solution of Bess increase electricity revenues?

(b) shows that the dispatching solution of BESS in general procures energy during low-price low-load periods and sells energy during high-price high-load periods, which increased the electricity revenues.

Why are battery energy storage systems used in microgrids?

Hence, battery energy storage systems (BESSs) are widely used to balance the power and shave peaks in microgrids . Furthermore, BESSs can be scheduled to increase the electricity revenue for microgrid entities by charging energy in low-price periods and discharging energy in high-price periods .
