The invention discloses a spot market volatility-based power package design method, which comprises the following steps of setting a user market constraint condition according to a user load curve, auser power package and a user demand response characteristic; introducing a spot market price fluctuation coefficient, and establishing an upper-layer model taking the optimal economic benefit of thee-commerce as a target and a lower-layer model taking the minimum total cost of the user as a target; and repeatedly iterating and deciding the contract electricity price and the demand response subsidy price by utilizing the upper-layer model and the lower-layer model until an iteration termination condition is met. By constructing the nonlinear double-layer model, the problem of how to design ascientific user power package in spot market competition of an electricity seller is solved, and market economic risks are avoided; meanwhile, the enthusiasm of user demand response can be aroused, and the user can enjoy the preferential electricity price.
Description
technical field [0001] The invention relates to the technical field of electric power market, in particular to an electric power package design method based on spot market volatility. Background technique [0002] With the advent of the global marketization trend, the power industry has gradually changed from monopoly to competition. As the core factor of the power market - electricity price, its structure and level have undergone major changes. The price of electricity changes with demand, and the change of electricity price also affects the demand. The role of the electricity price adjustment mechanism is more obvious. Compared with load, spot electricity price has strong volatility and is affected by more uncertain factors, such as system supply and demand situation, instability of fuel price, volatility of hydroelectric power station, transmission congestion, behavior of market members , system and unit constraints, etc. [0003] Foreign electricity sales markets are r...
