Risk-Averse Two-Stage Distributionally Robust Economic Dispatch Model Under Uncertain Renewable Energy
With the participation of large quantities of renewable energy in power system operations
their volatility and intermittence increases the difficulties and challenges of power system economic scheduling. Considering the uncertainty of renewable energy generation
based on the distributionally robust optimization method
a two-stage economic dispatch model is proposed to minimize the total operation costs. In this paper
it is assumed that the fluctuating of renewable power generation follows the unknown probability distribution that is restricted in an ambiguity set
which is established by utilizing the first-order moment information of available historical data. Furthermore
the theory of conditional value-at-risk is introduced to transform the model into a tractable model
which we call robust counterpart formulation. Based on the stochastic dual dynamic programming method
an improved iterative algorithm is proposed to solve the robust counterpart problem. Specifically
the convergence optimum can be obtained by the improved iterative algorithm
which performs a forward pass and backward pass repeatedly in each iterative process. Finally
by comparing with other methods
the results on the modified IEEE 6-bus
118-bus
and 300-bus system show the effectiveness and advantages of the proposed model and method.
