Grid Connected Photovoltaic Power Generation Station and it's Influence on Dispatching Operation Mode

To analyze the influence of distribution network with grid-connected photovoltaic (PV) generation on the power supply reliability, in this paper it firstly regards interconnected PV generation as an equivalent generator with rated capacity as well as the island operation mode of PV to set up a model for reliability calculation and analysis. Based on the network equivalent method, the structure of distribution system with PV is simplified and then the reliability indexes of distribution system are worked out based on Failure Mode and Effects Analysis (FMEA). At last, a comparative calculation between the distribution network with incorporated PV generations and that without PV generations is made. After analyzing a real example, the results suggest that integrating PV power generations reasonably into the distribution network can enhance the reliability of whole distribution system.

Photovoltaic Power

Photovoltaic power generation refers to the use of solar photovoltaic cells to the solar radiation can be directly transformed into electricity generation. Distributed photovoltaic power generation, refers to the construction in the vicinity of the user's location, the operation mode to the user side of spontaneous self-occupied mainly, the excess power on the Internet, and in the distribution system to balance the characteristics of the photovoltaic power generation facilities. Distributed photovoltaic power generation follow the principle of local conditions, clean and efficient, decentralized layout, the principle of the nearest use, and make full use of local solar energy resources, alternative and reduce fossil energy consumption. This paper aims to investigate and emphasize the importance of the grid-connected PV system. The investigation was conducted to critically review the literature on expected potential problems associated with issues of PV based grid system. The main purpose of this paper is to discuss the basic understanding of photovoltaic (PV) based distributed generation power system and how these power flows will influence the performance and stability of a power system. Some of the PV grid integration issues such as voltage regulation, voltage sags, harmonic distortion, etc are also discussed and possible solutions are also mentioned.

Suitable Power

We use PVsyst software to simulate and calculate the first year electricity generation of 4 MW distributed photovoltaic power generation project. In order to analyze and select the suitable power plant operation mode, the total generating capacity of photovoltaic power station in 25 years has been estimated by using component attenuation of 25 years. This research reports on the findings shown by PVsyst software that evaluates the economy aspects brought by two kinds of operation modes which are full grid access mode and spontaneous use of residual power grid access mode. The research content has reference value for the construction of roof distributed photovoltaic power station in China.
