Zhejiang first ChuChong integrated micro operation of light

Article 16 the regulation of power supply enterprises guaranteed supply situation. Already joined the user of the otc and exit, through the power purchase or sell electricity companies participate in the market transaction before, again by the power grid enterprise liable guaranteed power supply. Guaranteed power supply price according to the provincial development and reform commission published standards. Guaranteed electricity price, before the market users who applies for renunciation of transaction, the electricity price for a temporary sales price stipulated by the government.

on April 17, in zhejiang jiaxing power park, photovoltaic panels in the sunlight, the capacity has reached 4208 KWH, is building power supply to the park. It was recently put into operation in zhejiang province first light ChuChong integration piconets. The project set of photovoltaic power generation and distributed energy storage device and charging pile, basic meet its energy demand, electricity for energy production and use in the grid can load is balanced basically, and can provide reference for pluripotent complementary comprehensive utilization research and data to support.

as the large-scale use of photovoltaic, wind power and other new energy, power grid structure, power management tend to be complex, the power quality control more difficult. Caused a large number of distributed energy storage device connected to the electricity grid tide more fluid, increase the risk of safe operation of power grid. Facing the new situation, deepen in jiaxing power of new energy, new load ( Energy storage) Research, especially in the energy under the trend of Internet, grid can complementary business feasibility study, including the new energy project site selection, investment cost accounting earnings, investment recovery period, etc. , in order to better adapt to the energy demands of the development of the Internet.

at the beginning of this year in jiaxing power supply company to carry out comprehensive energy pilot application research, the investment in construction of photovoltaic power generation, power park distributed energy storage device and charging pile in a body's comprehensive energy pilot projects. Projects in the feasibility study, on the basis of fully using photovoltaic building integrated mode, building roof construction capacity of 812 in the park. 8 mw photovoltaic panels, are first meet the demand of building electricity production, given in the form of spontaneous self-use, yu electrical access to the Internet. Photovoltaic panels adopted conventional single crystal and rigid copper indium gallium selenide thin film two panels, facilitate comparative study efficiency. At the same time, the park construction capacity of 50 kw / 100 kilowatt-hours ( Meet 50 kw power equipment charging 2 hours) Distributed energy storage device, and according to the zhejiang province peak GuShiDuan formulating charging and discharging strategy, research on energy storage in peak cutting effect and economic benefit. In addition, four in the park, a total of 50 kilowatts of electric vehicle charging pile, the electricity generated by pv carport for electric vehicle charging. According to the feasibility study, project operating period of 25 years.

the light conditions according to April and jiaxing region, with an average sunshine time 5 hours, maximum capacity of 500 KWH, micro optical ChuChong integrated network can realize power above 2000 KWH each day, basic meet the demand of park building production of electricity and electric vehicle charging, can realize micro energy production and use in the grid load the basic balance. Flexible interaction at the same time, the network and the public power grid and relatively independent operation, not only reduces the distributed energy sources such as photovoltaic, charging pile the influence of the safe and stable operation of power grids, and improve the energy conversion efficiency, save land resource, improve the new energy utilization.

it is understood that the light ChuChong comprehensive energy is pilot project of jiaxing power supply company in an innovation try on new energy development and utilization. At the same time, the project as a test sample, the micro network run data for the photovoltaic conversion efficiency, photovoltaic power change trend of the change and the influence of the distributed energy storage for grid technology level, etc, to provide theoretical and data support.
