Cooperation mode of photovoltaic power station
For the application of distributed photovoltaic power plants, State Grid Corporation of China allows the owners of photovoltaic power plants to adopt three grid-connected settlement methods: spontaneous self-use, spontaneous self-use, surplus electricity connected to the Internet and complete access to the Internet.
1. Spontaneous self-use means that the power generated by distributed photovoltaic power plants is used by power generation enterprises themselves. This model is suitable for manufacturing enterprises that need long-term and lasting electricity, and the demand on the electricity side is large, which can completely or mostly absorb the electricity generated by photovoltaic power stations. When the power load of an enterprise is less than the power generation capacity of a power station, the surplus power cannot be sent to the power grid, which is also its main feature. In order to avoid power reverse transmission, it is necessary to configure an anti-reflux device to give an alarm, and the inverter will adjust its capacity according to the received signal. Of course, when the power generation of power stations is in short supply, power companies can also turn to the power grid for help. With the development of energy storage technology, some enterprises use energy storage equipment to carry out peak regulation and frequency modulation of electricity, so as to better maximize the utilization of photovoltaic power stations.
To sum up, the advantage of this grid-connected mode is that it is relatively independent, and it has very obvious economic benefits for enterprises with large demand for electricity. This grid-connected mode can also be selected for areas where power transmission is limited or photovoltaic power generation is not supported.
Photovoltaic power stations adopt the grid-connected settlement mode of spontaneous self-use, and the generated power is 100% absorbed by power consumption enterprises. The electricity consumption enterprise is an enterprise engaged in R&D and manufacturing of complete vehicles and spare parts, and the demand for electricity is huge, so the mode of spontaneous self-use is more suitable.
2. Spontaneous self-use and surplus electricity online, as the name implies, means that enterprises only use part of the power generated by distributed photovoltaic power plants, and the remaining electricity is sold to power grid companies. This model is suitable for enterprises with small power demand in production. For this kind of enterprises, spontaneous self-use and surplus electricity access to the Internet are the most ideal grid-connected modes. After all, while enterprises enjoy clean and low-cost green electricity, the rest will be sold to power grid companies to obtain corresponding income, killing two birds with one stone. However, the premise is to reach an agreement with the power grid company in advance, set the electricity price according to the power consumption of the enterprise, and install a two-way meter by the power grid company to count the power generation of the power station and the electricity consumption of the enterprise, so as to avoid conflicts in the case of unequal information.
Most of the power stations cooperated by Shanghai Pei 'an adopt this grid-connected mode, in which only 50% of the electricity is used by the enterprises themselves, and the rest are all connected to the internet to obtain electricity fee income. Photovoltaic power station not only helps the green development of enterprises, but also brings economic benefits.
3. Full access to the Internet means that the power generated by distributed photovoltaic power plants is directly connected to the power grid company, and the electricity used by enterprises is obtained from the power grid.
This grid-connected mode is the most mainstream and simplest in the past decade. After all, subsidies in various places were relatively strong before. For enterprises, while enjoying the original electricity price, the extra electricity price income of power stations is also very considerable. Nowadays, with the popularity of photovoltaic power plants, subsidies from various places have been cancelled one after another, and photovoltaic has also ushered in the era of cheap internet access. This model will gradually be weakened under the background of the times, which invisibly expands the space of power station transfer market.
Through sharing, I believe you have some understanding of the above three grid-connected modes. In the process of application, enterprises need to analyze specific problems, and choose the most suitable way according to the installed scale of photovoltaic power station, power generation, enterprise's own electricity consumption, electricity consumption cycle, local policies, local electricity prices and other related factors.
In this process, Shanghai Pei 'an will also provide professional services for everyone. On the one hand, it will help enterprises build distributed photovoltaic power stations through roofs to revitalize idle resources; On the other hand, through the AI management system, the photovoltaic power station is intelligently operated and maintained.
