Embodiment Construction

[0065] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] With the development of new communication technology and control technology, real-time pricing makes it possible to respond to each other on the "source-load" side. Through the regression analysis between new energy, load and market clearing price, the present invention excavates the correlation characteristic function between new energy and its real-time electricity price, and thus proposes a real-time power supply and sale pricing method considering the "source-load" supply and demand balance.

[0067] Such as figure 1 As shown, the pricing method of the new energy real-time electricity price of the present invention includes:

[0068] On the supply side, the standardization-Euclidean distance is used to mine the relevant factors affecting the real-time electricity price of new energy, including the system electricity price,...

Abstract

The invention discloses a new energy real-time electricity price pricing method, which comprises the following steps of: on a supply side, mining related factors which influence the new energy real-time electricity price by using a standardization-Euclidean distance, including a system electricity price, a new energy predicted internet surfing quantity and a load demand predicted quantity, and proposing a fitting function relationship between each related factor and a new energy real-time power supply price; on the demand side, the function relation between the electricity selling price and the load size is expressed through a price demand response elastic matrix; the function relation on the two sides is included in a cost-benefit target, and a min-max model is established and serves as a real-time power supply and sale pricing model of source-load real-time supply and demand; under the condition of considering different scenes, a min-max multi-scene objective function is established, and the model is converted and solved by using a Lagrange optimization duality theory. The method has the advantages of being simple in principle, easy to implement, capable of stabilizing load fluctuation, capable of improving new energy consumption and the like.

Description

technical field [0001] The invention mainly relates to the technical field of power operation, in particular to a pricing method for real-time electricity prices of new energy sources. Background technique [0002] With the rapid development of grid-connected renewable energy, the research on its electricity price also shows a trend of diversification. At present, electricity prices for new energy power generation are composed of costs and subsidies: costs are mainly based on financial accounting methods, such as the use of estimated construction costs, energy saving costs, operation and maintenance costs, and environmental values ​​to formulate electricity price standards. Due to the high initial investment cost of renewable energy development, various countries have adopted various relevant subsidy policies to ensure the income of units in order to encourage the development of renewable energy: my country's current electricity price policy for renewable energy is a fixed b...
