Embodiment Construction

[0072] The specific implementation steps of a virtual power plant optimal scheduling and transaction management method considering green certificate transactions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0073] Such as figure 1 Shown, the present invention comprises the following steps:

[0074] Step 1, the optimal scheduling of VPP needs to consider the influence of uncertainty: use the truncated general distribution model to fit the actual new energy output, obtain the probability density curve of new energy output, and use Latin hypercube sampling to obtain typical new energy output scenarios and the corresponding probability;

[0075] Step 2: Construct a three-stage VPP deterministic model with the goal of maximizing the profit of virtual power plant (VPP) participating in power transactions and green certificate transactions; the three-stage benefits of VPP include: medium and long-term green power-green c...

Abstract

The invention discloses a virtual power plant optimization scheduling and transaction management method considering green certificate transaction, and the method comprises the steps: employing a TVD (Truncated Versatile Distribution) model to fit new energy output according to the actual data of a wind power station and a photovoltaic station, constructing a virtual power plant optimization scheduling model taking the maximum profit of a virtual power plant as an optimization target, and constructing a model constraint condition; solving the virtual power plant optimal scheduling model by adopting stochastic programming and a heuristic algorithm, and simulating the influence of participation of the virtual power plant in green certificate transaction.

Description

technical field [0001] The invention belongs to the field of power supply dispatching in electric power systems, and in particular relates to a virtual power plant optimization dispatching and transaction management method considering green certificate transactions. Background technique [0002] The development of renewable energy has become a major strategic move for low-carbon energy transition and response to global climate change. my country's early green energy power generation mainly relied on government support, and adopted a fixed electricity price system (feed-in tariff, FIT) to promote the development of renewable energy. At present, my country's wind power and photovoltaic installed capacity ranks first in the world. However, with the rapid development of domestic renewable energy installed capacity, the subsidy gap for renewable energy is also increasing. In order to alleviate the subsidy pressure and stimulate the enthusiasm of renewable energy power generator...
