Abstract：There is a highly coupled space-time hydraulic connection between cascade hydropower plants, and due to the different locations in the basin and adjustment capabilities, the market competitiveness and quotation flexibility of various hydropower plants vary greatly, which increases the difficulty and risk of bidding in the spot market. Participating in the market with quotation units is beneficial to resist risks, but how to choose partners is very important. Based on runoff connections in the basin, this paper introduced the concept of "virtual reservoir" and put forward a new spot quotation unit construction method of cascade hydropower, then designed a complete bidding process in the spot market for the quotation unit. A two-layer simulation model was established based on the interests of both power purchase and sales. Finally, a case study was carried out with a cascade hydropower quotation unit in a river basin in Sichuan Province. The results show that participating in the market with a “virtual reservoir” quotation unit can increase the market share of each member, expand the quotation space, reduce market risks, increase net income, and at the same time reduce the purchase cost of electricity, which verifies the scientificity and correctness of the quotation unit based on the “virtual reservoir”.
