An efficient primal-dual approach to chance-constrained economic dispatch

摘要: To effectively enhance the integration of distributed and renewable energy sources in future smart microgrids, economical management accounting for principal challenge variable non-dispatchable renewables is indispensable significant importance. Day-ahead economic generation dispatch with demand-side a micro-grid islanded mode considered this paper. With goal limiting risk loss-of-load probability, joint chance constrained optimization problem formulated optimal multi-period scheduling multiple wind farms. Bypassing intractable spatio-temporal distribution power generation, primal-dual approach used to obtain suboptimal solution efficiently. The method based on first-order optimality conditions successive approximation probabilistic constraint by p-efficient points. Numerical results are reported corroborate merits approach.
