In the first quarter of 2019, the operating area of state grid corporation of China (hereinafter referred to as "state grid") generated 115.8 billion KWH of new energy, up 10% year-on-year, with new energy generation accounting for 9.1%, up 0.7% year-on-year. The electricity abandoned by new energy sources reached 4.66 billion kilowatt-hours, down 31% year-on-year, and the electricity abandoned rate was 3.9%, down by 2.1 percentage points year-on-year. That's the message from the state grid's press conference on promoting clean energy development on April 11.

 

The year 2019 is a crucial year to promote the consumption of clean energy. As the world's largest power grid connected to clean energy, state grid plans to achieve the goal of new energy utilization rate above 95% ahead of schedule. Therefore, it will further study and propose a number of new measures to promote the high-quality development of clean energy.

 

New energy consumption channels have been expanded

 

Half of the solar panels in the gobi desert bask in the empty sun, as a reporter for the economic information daily saw in dunhuang, gansu province, six years ago. At that time, the installed capacity of new energy in the province grew rapidly, but its own consumption was limited, and the development of power grid lagged behind due to the long period of approval and construction, leading to the phenomenon of "abandoning wind" and "abandoning light".

 

Starting in 2014, though, things got better. Since the 12th five-year plan, a total of 76 billion yuan has been invested in gansu's power grid. The first and second channels of 750 kv and a series of 330 kv transmission projects have been built to meet the needs of new energy project access and transmission. In August 2017, the world's first uhvdc project to transport new energy from jiuquan to hunan province was completed and put into operation.

 

The expansion of new energy consumption channels is not limited to this, "marketization" is one of the new paths in the past two years. For example, through medium - and long-term joint export of new energy and thermal power, gansu delivered 32.5 billion KWH of electricity in 2018, an increase of 60.17% year on year, and 3.332 billion KWH of new energy more than in 2017. There were also cross-provincial spot transactions of surplus new energy, with 3.249 billion kilowatt-hours of electricity completed, accounting for 46.7% of the total trading volume of the state grid.

 

In recent years, China's clean energy has witnessed sustained and rapid development. By the end of 2018, China's total installed clean energy capacity had exceeded 700 million kilowatts, accounting for 30% of the global total. In 2018, the national development and reform commission (NDRC) and the national energy administration (nea) made it a priority to promote high-quality development of clean energy and effectively solve the problem of clean energy absorption.

 

According to the report, the state grid has formulated and implemented 22 measures to promote the consumption of new energy, including power grid construction, dispatching and operation, market trading, technological innovation and other aspects, achieving remarkable results. According to the data, by the end of 2018, the total installed capacity of clean energy power generation in the company's operation area was 550 million kw, accounting for 73% of the country's total installed capacity and 38% of the total installed power capacity. Clean energy generated 1.2 trillion kilowatt-hours, up 11 percent year-on-year. It accounts for 22.8 percent of total power generation, up 0.5 percentage points year-on-year. Electricity abandoned by new energy sources reached 26.8 billion kilowatt-hours, down 35 percent year-on-year, and the electricity abandoned rate was 5.8 percent, down 5.2 percentage points year-on-year. In southwest China, 13.8 billion kilowatt-hours of hydropower were abandoned in peak regulation, down 14% year-on-year, and the water abandoning rate was 3.8%, down 0.8 percentage points year-on-year.

 

We will promote cross-regional and cross-provincial consumption of clean energy

 

The year 2019 is a crucial year for promoting clean energy consumption. The government work report proposes to vigorously develop renewable energy and accelerate efforts to solve the problem of wind, light and hydropower consumption.

 

"The problem of new energy consumption has been alleviated on the whole, but problems still exist in some areas. In 2018, the electricity abandonment rate of new energy in xinjiang and gansu will still be above 15%. Liu jinsong, deputy director of the state grid development department, explained that there are still many uncertainties in new energy consumption in 2019.

 

Liu jinsong revealed that in 2019, state grid will carry out planning research in advance, coordinate the development and consumption of new energy, and put forward Suggestions on the installed scale, layout and timing for government departments to promote orderly development. At the same time, we will continue to strengthen the construction of power grids and expand the scope of clean energy allocation. We will accelerate the construction of transmission channels for the zhangbei-xiongan uhv ac, qinghai-henan, yaxin-jiangxi, shenbei-wuhan uhv dc and zhangbei flexible dc demonstration projects. Within this year, 17 provincial cross-section strengthening projects including the 750kv third corridor of gansu hexi corridor were completed and put into operation.

 

It is worth noting that in the work conference of state grid corporation of China in 2019, chairman kou wei proposed the new era strategic goal of "three types, two networks and world-class" to promote the construction of world-class energy Internet enterprises. Including, fully application of modern information technology such as mobile communications, artificial intelligence and advanced communication technology, the implementation of each link all interconnected power system, human-computer interaction, make state comprehensive perception, information efficient processing and application is convenient and flexible in the power of things, safe and economic operation for the grid to provide powerful data resources and new energy given.

 

"" we need to accelerate the construction of the ubiquitous power Internet of things, explore a long-term mechanism to serve the development of new energy, and promote the coordinated development of the power grid and the Internet of things." " Liu, according to the national grid will development of new energy big data management platform, focusing on the company's core business, focusing on government social concern, focusing on customers, focus on the value function, in order to satisfy the demands of the subject as the guidance, ascension grid business all links work efficiency and service level, provide support for the development of new energy, high quality.

 

In addition, state grid will also build a unified national electricity market and expand the space for clean energy consumption. We will promote the improvement of policies, markets and price mechanisms that are conducive to breaking down barriers between provinces and promoting cross-regional and cross-provincial consumption of clean energy, and give full play to the decisive role of the market in resource allocation. We will give top priority to ensuring that clean energy is involved in medium - and long-term inter-provincial transactions, and adopt a variety of market-based trading methods to promote clean energy consumption. We will vigorously promote the replacement of electric power, and strive to complete the replacement of more than 145 billion kilowatt-hours in 2019.

 

We will work together to promote high-quality development of clean energy

 

State grid energy institute, deputy director of the institute of new energy and statistical tse kwok fai think clean energy given is a worldwide problem, countries such as Denmark, Germany, Spain, Portugal's experience is worth reference for clean energy development, ultimately is the establishment of a "policy, market guide" clean energy given a long-term mechanism.

 

In recent years, the national development and reform commission and the national energy administration have introduced a series of measures, including an investment monitoring and early warning mechanism, adjustment of electricity prices, competitive allocation of projects, and affordable access to the Internet.

 

"With the advent of parity era, it is still necessary to further improve the monitoring and warning mechanism of wind power and photovoltaic power generation investment, regularly issue annual warning results, and guide the rational distribution of wind power and photovoltaic power generation. Xie suggested that the unified planning mechanism of power supply and power grid, new energy and various power sources should be improved. We will improve the market mechanism for promoting clean energy consumption, establish and improve the mechanism for clean energy to participate in intra-provincial and inter-provincial market transactions, and the compensation mechanism for thermal power peak regulation, and encourage clean energy power generation to participate in the spot market. We will improve the policy for purchasing renewable energy on a guaranteed basis and ensure that priority power generation is linked to market-based consumption.

 

In terms of power supply, the annual construction scale, layout and timing of clean energy should be reasonably determined in accordance with the consumption target of each region and the local power grid connection conditions and consumption capacity. State grid proposed to accelerate the implementation of flexible transformation of thermal power units, and strive to complete the transformation scale of over 40 million kilowatts in 2019. The construction and operation management of coal-fired self-provided power plants shall be standardized, and the grid-connected coal-fired self-provided power plants shall be under the same management as public power plants, subject to unified dispatching by the power grid, and assume peak-load regulation obligations and corresponding social responsibilities. To improve the network-related performance of new energy stations and provide support for the high proportion of access and operation of new energy.

 

Xie guohui believes that users should advocate green development mode, explore new ways to "replace coal with electricity" and "replace oil with electricity", and increase the proportion of electric energy in the terminal energy consumption.
