Method & Evidence

AimHow can the integration of energy storage systems with generalized demand-side resources, considering uncertainties, optimize the operational cost of distribution networks?

MethodMathematical optimization, simulation, and probabilistic modeling

ProcedureThe study developed a configuration model for generalized demand-side resources (including translational and reducible loads, and energy storage systems). It then established a deterministic model to minimize operational costs, followed by a fuzzy chance-constrained programming approach to incorporate uncertainties from demand response, renewable energy prediction errors, and non-participating resources. Monte Carlo simulations were used to refine energy storage capacity based on daily operations.
