Embodiment Construction

[0122] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0123] Such as figure 1 Shown is a virtual power plant construction and output optimization method under the tradable energy mechanism, combined with figure 2 and image 3 Describe the entire implementation process in detail.

[0124] Step 1: According to the accuracy of wind power output forecast data before the day, calculate the potential wind turbine trading demand in the next day's deviation trading market.

[0125] Based on the forecast deviation of wind power, the transaction demand for wind turbine up-regulation and down-regulation is calculated respectively:

[0126]

[0127] In the formula, both are variables at time t, where: and Respectively, the upward and downward transaction demand expectations of wind turbine clusters, is the predicted power value of the i-th wind turbine, is the actual output of the i-th fan, and ...

Abstract

The invention discloses a construction and output optimization method of a virtual power plant under a tradable energy mechanism, and belongs to the technical field of calculation, reckoning and counting. The construction and output optimization method comprises the steps: calculating a potential transaction demand of a fan in a next day deviation value transaction market according to the accuracyof wind power output day-ahead prediction data; selecting high-quality transaction partners for the fans in numerous air conditioner resources by taking maximization of expected income as a target, and jointly forming a virtual power plant for bidding in the day-ahead market; reporting a real-time to-be-transacted deviation value and a corresponding transaction price in the virtual power plant internal deviation value transaction market by the fan and the air conditioner; organizing real-time bidirectional auction by a virtual power plant operator; and reducing overall external output deviation of the virtual power plant through deviation transaction between internal resources, and guiding the virtual power plant to provide output according to a day-ahead plan in a transaction mode, so that dynamic balance of power grid supply and demand can be promoted, and mutual benefit and win-win between distributed resources and virtual power plant operators can be achieved.

Description

technical field [0001] The invention discloses a construction and output optimization method of a virtual power plant under a tradable energy mechanism, relates to a power system and its automation technology, and belongs to the technical field of calculation, calculation and counting. Background technique [0002] In recent years, with the large-scale access of distributed resources such as new energy generators, energy storage systems, and electric vehicles, the uncertainty of their power generation and consumption has brought great challenges to the balance of supply and demand in the power grid. In the context of the ubiquitous power Internet of Things, many user-side devices can fully apply modern ICT technologies such as mobile Internet and artificial intelligence to realize the interconnection of all aspects of the power system. The flexible load typically represented by air-conditioning equipment can realize the adjustment of power consumption through demand response...
