Problems solved by technology

However, due to the characteristics of wind power and photovoltaic power generation, connecting these two renewable energy sources to the power system will bring certain challenges to the system. At the same time, my country is actively promoting power reform at this stage, and the power system has gradually entered the market. At present, there is no mid-to-long-term power planning plan that takes renewable energy into account, which leads to a decline in the utilization rate of renewable energy and misallocation of resources due to information asymmetry

Embodiment 1

[0121] In this example, the simulated power system adopts IEEE14 node and IEEE39 node system.

[0122] In the IEEE14 node system, according to the distribution of active loads and units in the original data, two wind farms with a rated capacity of 50MW and a photovoltaic power station with a rated capacity of 35MW were added. The wind farm and the photovoltaic power station are located at node 4 and node 13 respectively. and node 9. The total installed capacity of wind farms and photovoltaic power stations is 135MW, the total installed capacity of thermal power units is 320MW, and the installed capacity of wind power and photovoltaic power generation accounts for about 30% of the total installed capacity. In the calculation example in this chapter, the generator set is regarded as a power generation enterprise, and the load node is regarded as a power user.

Abstract

The invention relates to an electric quantity distribution method with renewable energy participating in medium-and-long-term power transaction. The electric quantity distribution method comprises thefollowing steps: 1) according to clearing data of an energy market, formulating a declaration electricity price of a power generation enterprise; 2) according to a two-layer planning theory, establishing a two-layer planning model in which renewable energy participates in medium-and-long-term power transactions; and 3) solving the two-layer planning model by adopting a hybrid algorithm combiningthe discrete particle swarm and the continuous particle swarm and a nonlinear planning method, and completing the distribution of the electric quantity of the power generation enterprise and the electricity price of the power user according to the obtained optimal solution. Compared with the prior art, the electric quantity distribution method has the advantages of accurate distribution, practicability, reasonableness and the like.

Description

technical field [0001] The invention relates to the field of electric power market, in particular to a power distribution method for renewable energy to participate in medium and long-term power trading. Background technique [0002] With the rapid economic development, energy and environmental issues have become the focus of the world today. The demand for energy such as coal, oil, and natural gas is increasing day by day, but these energy sources are non-renewable, and will cause serious pollution to the environment during the utilization process, and the impact on the healthy development and stability of society is also increasing. Therefore, renewable energy power generation It has received more and more attention, and wind power and solar power will become the main force of my country's future energy structure. [0003] With the support of government policies in various countries, after years of research, wind power and photovoltaics have become relatively mature new en...
