“…Nowadays, the pressure of wind power curtailment is still the constrained factor for wind electricity to meet the electricity demand. In the future, the wind power curtailment situation will be improved with the strengthening of the power grid technology improvement in the two regions of China, particularly the completion of the UHV line as the main channel of wind power transmission [42][43][44]. In the long term prognosis of the power system, electricity generated based on renewables may meet the entire electricity demand ultimately.…”

Electricity consumption is often the hotspot of life cycle assessment (LCA) of products, industrial activities, or services. The objective of this paper is to provide a consistent, scientific, region-specific electricity-supply-based inventory of electricity generation technology for national and regional power grids. Marginal electricity generation technology is pivotal in assessing impacts related to additional consumption of electricity. China covers a large geographical area with regional supply grids; these are arguably equally or less integrated. Meanwhile, it is also a country with internal imbalances in regional energy supply and demand. Therefore, we suggest an approach to achieve a geographical subdivision of the Chinese electricity grid, corresponding to the interprovincial regional power grids,

“…China's wind curtailment is characterized by imbalance of regional development of wind power [7]. The contrary distribution of the wind resource and load and the large-scale concentrated development make China a country with the highest access voltage and the longest transmission distance of wind power [8].…”

“…Different from Germany, Spain and Denmark that feature dispersed distribution and local consumption of wind power, China normally transmits the wind power through the high voltage line to a long distance. The wind power base of Jiuquan transmits the surplus wind power to the load center 1000 km away; the wind power base of Inner Mongolia also transmits the wind power to consumers more than 250 km away [7]. Provinces in western and northern China that enjoy abundant wind resources are far from the electricity consumers in eastern China, resulting in the high rate of wind curtailment.…”

“…Large-scale wind curtailment became frequent and normalized in northeast and northwest China. The rationed electricity of Gansu, Inner Mongolia, Jilin and Heilongjiang reached 5304 GWh, accounting for 50% of China's total; and the national electricity rationing reached 14.5% [7]. The year 2012 saw the most serious wind curtailment in history and the total rationed wind power hit 20,800 GWh, more than two times of that in 2011, accounting for 14.7% of the total wind power output of the year, the highest in history [7].…”

Why the Wind Curtailment of Northwest China Remains High

et al. 2018

Abstract:The total grid-connected installed capacity of wind power in northwest China has grown from 16,260 MW in 2013 to 43,290 MW in 2016; an increase of 88.7% each year. However, this region has suffered from increasingly serious wind curtailment since 2014, and the wind curtailment amount accounts for nearly a half of China's total. The wind curtailment rate of Gansu Province, Xinjiang Uygur Autonomous Region and Ningxia Hui Autonomous Region in this area has increased and remains high. This paper constructs an analytical model to explore the reasons of the high wind curtailment of these three provinces from the four aspects of the wind power supply capacity, demand, grid transmission capacity, power system flexibility and market mechanism and laws. The results show that the relationship between the wind energy distribution and supply and the local load is incompatible, which is the source causing the high wind curtailment in northwest China. On the one hand, the game between the local government and developers has driven the development of wind power bases. On the other hand, the electricity sector is growing slowly and oversupply of electricity is seen in many areas of China. The wind power grid of northwest China not only faces limit of grid transmission capacity, but also constraint of insufficient flexibility of the electricity system. Presently, China has not set up a market mechanism and subsidy mechanism for the peak load adjustment, thus the thermal power companies lack motivation to voluntarily adjust the peak load. Moreover, the regional segregation and market barriers are also obstacles for the wind power outward transmission.

Optimum Subsidy to Promote Electric Boiler Investment to Accommodate Wind Power

Abstract:The increasing development of combined heat and power (CHP) plants is exacerbating the wind power curtailment problem in regional power grids during the winter heating season. Electric boilers (EBs) were proposed to be employed within CHP plants to relieve this problem. However, CHP plants usually have no incentive for investing in EBs. Therefore, CHP plants must be incentivized to make such investments through appropriate compensation from beneficiaries, i.e., government and wind farms, although this has not previously been discussed. We propose a game theory model to simulate the impact of government subsidies on EB investment. We analyzed the utilization of the involved parties with the marginal cost and average cost and applied game theory to simulate the investment decisions. Then, an approximate enumeration technique was developed to identify the optimum government subsidy. An actual case of a regional power grid in northern China was investigated to validate the proposed method. A minimum government subsidy to maximize total social benefit was calculated; this subsidy can incentivize wind farms and CHP plants to invest in and use EBs.
