Battery maker dance for joy

India's state-owned energy company general manager in an interview said that the company will be responsible to implement the government's green goals, in the southern Indian city of Andhra Pradesh 750 megawatt solar project subject to tender, will be required to tender have 100 megawatts of energy storage facilities.

The purpose of the pilot program is to reduce the fluctuations in the power supply, so that the transfer of the state's clean energy transfer is possible. The Prime Minister of India NarendraModi is set to 2022 domestic clean energy installed capacity reached 175 GW target. Energy storage project will be divided into two parts, each part can provide 15 minutes of power storage.

Storage can be regarded as an important part of India's green goals. If this standard is widely used, it will stimulate the potential of India's energy storage market. This will expand the size of the relevant manufacturers, helps to reduce the cost of storage battery, so that the energy storage devices are more widely used.

"If renewable energy installed capacity is large enough, for the grid produced new problems. This means that energy storage of the era," said KPMG consulting firm infrastructure and government services analyst AnishDe. Global battery manufacturers are generally optimistic about the project in India.

"Exciting market opportunities"

Located in Palo Alto, the Tesla in the third quarter of last year to shareholders letter mentioned, see the company's is a "exciting market opportunity". An unnamed Samsung SDI spokesman said the company is currently assessing the commercial nature of PV + energy storage projects, together with the micro grid project to provide environmentally friendly energy for remote areas". Panasonic Corp in the local energy business executives HirenPravinShah said that Panasonic is specifically for the India R & D suitable products.

According to Bloomberg new energy finance data, by 2020, global will install 11.3 GWH storage project, 1% less intermittent renewable energy in the total installed capacity. BNEF London energy storage analyst LoganGoldie-Scot said that the current important energy storage project is located in the United States, South Korea and japan. According to a report released by the industry observer HIS last month, to 2018, due to the rise in electricity prices, Australia's energy storage market is expected to double every year.

Cost is the main factor restricting the development of

Logan said: "recent moves by the India market have indicated that the government and the private sector are hoping to fill the space with the advantage of cost reduction and performance improvement." At the same time, India's renewable energy industry is concerned that the high cost of energy storage projects will limit the development of this industry, so that investors once again tend to use fossil fuels to balance.

In January of this year, in the Indian state of Rajasthan created the lowest record in solar power prices in India, per kWh 4.34 rupees (about 6 cents). The record by a 420 megawatt solar power station to create.

"It will is a good practice, but also not promote utilities vigorously the development of energy storage project the best time, because of the cost is twice the ordinary clean energy, or even said, SunilJain" hero group clean energy company's chief executive. According to Panasonic Corp's analysis, if the energy storage project is increased, the cost of photovoltaic power generation will reach 14 rupees per kilowatt hour (about 19 cents). Tesla's home energy storage device is the use of lithium-ion batteries, the cost is more than 4 times the traditional lead-acid batteries. Shah said: if the price fell to 1.5 times the lead acid battery, then the business will appear close to 70% growth rate." Government departments said that the first bid is just a small scale to try, the cost will not be too exaggerated, the main purpose is to assess how much electricity supply fluctuations can be resolved, the government will be funded to meet part of the cost of the problem.

By the end of 2016, China electric power will have more than 250 million kilowatts of capacity of the fan out of warranty, used to eat a factory payroll of the wind farm to be faced with self-reliance, autonomous device maintenance, maintenance into the one of the problems to be solved. From manufacturers to independent how the transition? Team is not professional how to do? In this regard, the state power has established a special New Energy Technology Co., Ltd., concentrated force to carry out personnel training, fan repair maintenance, increase reactive power optimization work, focused on solving plan maintenance and fault power loss problem.

Set up a centralized control center of Ningxia's new energy, in the centralized control, big data analysis has accumulated some experience. By 2015, Ningxia new energy will be more mature centralized control, data analysis and "theory of power balance analysis model organic combination, can quickly clarify the power loss, loss where and set up feasible measures according to the results of analysis, on the control model were good practice.

In hydropower, China electric power requires all units to continued to improve hydrological measuring and reporting system, to improve the accuracy of runoff forecast, find the loss of power is the key link, formulate effective measures in a timely manner, achieve waterpower utilization rate is maximized.

And Yu companies to seize the power loss of each link, relying on the "theory of power balance analysis method" management model, clear rules and requirements of the index of flood forecasting accuracy, flood season rainfall in the report, test report system patency rate etc. and also to "small target competition" to grasp the hand, improve employee sense of competition, enhancing the power of examination. After some specific measures of the implementation of the company, the company's equipment readiness rate, water use efficiency and other major indicators have a relatively large increase.

Fujian new energy Jie Zhu Kou hydropower station before the arrival of the hydrological and respond in a timely manner, through the dynamic water level regulation, and actively strive for during the low load and other effective measures, and ensure the generation capacity.

It easy to solve the problem of a loss of power factor, but the solution all is difficult, many hands may lead to drift indicators. To this end, the state electric power requirements: each unit must have the ability to stare at various loss items, can not be used as a measure of the decline in the final results of the standard.

In practice, the state electric power gradually formed from top to bottom, from outside to inside the scientific closed loop management means, for the theory of power balance analysis method to provide a reliable guarantee for the implementation of the normal.

Using specific results to verify the control model

"Without the support of digital results of concrete, the control model is equal to the empty talk."

China electric power requirements of hydropower, wind power related units, departments should refer to the thermal power fine management of the mature experience, for power losses, strict according to the theory of power balance analysis method to carry on the analysis, timely comparison summary.

Guodian power Anson, new energy industry, requirements of the relevant units a month reported the power loss, and drawn into the theory of generating capacity equilibrium diagram, who have achieved remarkable results, what aspects of the work needs to be strengthened, be clear at a glance.

Data comparison is to better identify and solve problems, for each unit in use "problems encountered when theory generating capacity equilibrium analysis", the state power according to the actual situation of guidance related units to formulate specific measures, reduce the proportion of larger loss, and effectively suppress the loss of electricity "bleeding".

By 2015, the Ningbo wind power have such a group of figures: wind energy utilization rate is as high as 97.96%, Ningbo wind power brownouts loss is 0, the loss of equipment failure 95 million kilowatts, plans to overhaul the loss of 71 million kilowatts, involved loss of 7.2 million kilowatts, performance loss 547 million kilowatts, total in energy loss and the theory of generating capacity 38463 million kilowatts compared, exactly is actual power generation 37678 million kilowatts. This five star enterprise, really sort out how much wind, how much electricity should be made, how much loss of power, loss of what the problem.

Last year, hydropower enterprises figures also show gratifying situation, Oujiang River hydropower, Qinghai new energy runoff plant increase with upstream regulating plant coordination efforts, and Yu companies through the cascade combination optimization of reservoir operation, reduce the overflow spillway energy loss is 560 million kilowatts. The station by means of dynamic water level regulation and high water pressure red line running to grab power generation capacity of 6.4 million kilowatts, which Fujian new energy Jiezhukou station through the regulation of the annual average water level optimization an increase of 0.74 m, and Yu company Huanren power plant make full use of runoff back to the storage capacity of the high water level.

China electric power through the model analysis, problem oriented, detailed work to implement, after continuous practice, water and electricity, wind power economic operation level significantly increased. Last year, the company's wind energy utilization was completed 1957; the use of hours to complete 9.33% hours, higher than the national average of 229 hours; abandoned wind rate of 5.67, lower than the national average of 86.77% percentage points. Hydroelectric power generation accounted for 5% of the total power generation, water use efficiency reached 86.16%.

The theory of power balance analysis method "management model of the establishment of, for Guodian hydropower, wind power and other fine management of renewable energy has a positive role, but also for enterprise level practice upgrade version of" double promotion "provide the direction and the method. 2016 is "45" at the beginning of the year, country electric power still in practice continuously grope and innovative, constantly looking for improve the level of economic operation and management of the better solution...
