Adopting Nonlinear Programming Method to Solve Multi - period Unit Price Quota and Generation Plan in Power Market. A multi-period power generation planning model considering pumped-storage power station is established. Based on the sequencing, the influence of transmission constraints and loss on the power generation plan is considered, and the optimal power generation plan that satisfies the quotation and grid constraints is obtained by using the nonlinear optimization method . The analysis of a 6-node bus system with multi-period power generation trade plan shows that the power transmission constraints and transmission losses have an impact on the power generation plan. Multi-period power generation plan optimization can bring greater global economic benefits
