Method for analyzing limitation factors of new energy power generation on power grid side

Abstract

The present invention provides a method for analyzing limitation factors of new energy power generation on a power grid side. The limitation factors of new energy power generation on the power grid side comprise the limitation caused only by peak regulation, the limitation caused only by the grid, and the limitation caused by the peak regulation-grid. The limitation caused only by peak regulation, the limitation caused only by the grid, and the limitation caused by the peak regulation-grid are analyzed separately by using a new energy production and simulation platform. According to the method provided by the present invention, results of limited electricity of new energy power generation under the ideal grid condition and the actual grid condition in the same power grid are simulated and calculated by using the new energy production and simulation platform, and the quantity of limited electricity of new energy power generation within the power grid dispatching range is divided into the quantity of limited electricity due to the peak regulation and the quantity of limited electricity due to the grid, so as to obtain impact degrees and weights of the two limitation factors to the limitation of the new energy power generation in the power grid separately. By virtue of the method provided by the present invention, the government administrative departments and the power grid dispatching agencies can clarify real factors for limitation of new energy power generation in the power grid, and then take targeted measures to reduce the quantity of limited electricity of new energy power generation in the power grid, so that improvement of the new energy power generation consumption level and utilization rate in the power grid, and the maximum use of clean energy can be facilitated.

Description

technical field [0001] The invention relates to an analysis method, in particular to a method for analyzing the reasons for the limited power generation of new energy sources on the grid side. Background technique [0002] The power system is a complex dynamic system, and its safe and stable operation essentially requires a balance between power generation and load demand at all times. If the power system cannot be effectively adjusted and there is an imbalance between supply and demand, it will affect the reliable power consumption of the load and may even cause a large-scale power outage in the system. [0003] New energy power generation represented by wind power and photovoltaic power generation has become an important form of energy in my country, and plays an important role in meeting energy demand, improving energy structure, reducing environmental pollution, and protecting the ecological environment. However, large-scale new energy power generation also brings enorm...

Problems solved by technology

In the "Three Norths" area where new energy power generation is abundant, the power supply structure is single, and the proportion of flexible and adjustable power sources that can effectively adapt to the fluctuation of new energy power generation is less than 3%, and more than half of the thermal power units accounting for 76% of the total installed capacity are heating units. In order to meet the heating demand in winter, the peak-shaving capacity of thermal power units is very limited

The intertwined influence of the two power-limiting factors makes it impossible to assess the weight and degree of influence of the two power-limiting reasons from the actual power-limiting of new energy power generation itself. Effectively reduce restrictions on new energy power generation, which is not conducive to the full utilization of clean energy
