Study on the Development and Consumption Mode of High Penetration of Wind Power and Solar Photovoltaic in Interconnected Power Systems
摘要
Abstract
Developing high penetration of wind and solar photovoltaic (PV) power generation is an inevitable choice to maintain ecological civilization and realize sustainable development of the society.On one hand,wind and solar PV power generation can be developed in areas near the load centers and consumed locally with extensive distributed wind and solar PV power generation systems,i.e.,the so-called "local development and consumption" mode.On the other hand,wind and solar PV power generation can also be developed in areas far away from the load centers with wind and solar PV bases and then the electricity generated there will be transmitted to the load centers by long distance transmission lines (e.g.by UHVDC lines),i.e.,the so-called "large-scale and long-distance transmission" mode.Nevertheless,how wind and solar PV power is developed and consumed will make a big difference to the smooth realization of high penetration renewable energy scene.The following conclusions have already been achieved in a study based on mathematical optimization approach that under the current situation that coal-fired thermal power units play the main role in peak load regulation,the only way to achieve high penetration of wind and solar PV power generation is with local development and consumption mode.To help readers understand the above conclusion better,firstly,in this paper,the basic features of interconnected power systems are introduced and compared with the basic features of the internet.Then,from the philosophy of interconnected power systems,a qualitative analysis and brief illustration are carried out to the two modes above in the following three perspectives:renewable energy electricity ratio,system operation and available regulation capacity.Finally,through a specific simulation case,the effective measures needed to help power system integrating high penetration of wind and solar PV power are displayed under the condition of taking the local development and consumption mode.关键词
