“…Because of clean and sufficient solar energy resources and convenient installation methods, such as "roof photovoltaic", the economic and environmental benefits of the PV generation system are continuously improved [3,4]. When a high proportion of distributed energy is connected to the power grid, the change in configuration and operation condition of the distribution network is huge [5] and the power flow of the distribution network has significantly been changed [6,7]. On the one hand, distributed PV will affect the power flow of the distribution network, directly affecting the loss of lines and equipment [8].…”

In a power system with highly proportional renewable energy integration, the power generated by photovoltaic (PV) of high permeability and high proportion needs to be connected to the distribution network through the power electronic inverter. The inverters can generate the low-order harmonic and high-order harmonic near the switching frequency. Harmonic power will be generated when the harmonic current flows through the power grid with the harmonic voltage of the same frequency, and the additional harmonic losses caused should not be neglected. To effectively analyze the voltage quality and calculate the harmonic loss of the low-voltage distribution network integrated with distributed PV, based on the harmonic loss factor of resistance proposed, the harmonic impedance modeling and harmonic loss calculation method for the key equipment of the power grid, such as lines and transformers, are introduced in this paper firstly. Next, a decoupling algorithm of harmonic power flow is proposed, and the influence of the access capacity of PV on voltage quality and line loss of the distribution network is analyzed. Finally, a harmonic loss calculation method based on measured harmonic data of the distribution network is proposed. It is found that the harmonic loss of the low-voltage distribution network accounts for about 0.6% of the total network loss. Therefore, voltage quality can be improved and line loss can be reduced effectively by reasonable access to PV and reducing harmonic order and the current harmonic distortion.

“…Therefore, when environmental protection is increasingly important, the utilization and development of renewable energy such as wind energy and solar energy will become an important energy strategic goal in the today [1][2]. However, the fluctuation and intermittency of photovoltaic power generation will bring stability problems to the power grid, and the application of a large number of power electronic devices will inject harmonics into the grid [3][4][5]. Therefore, it is a very important work to carry out the test of grid connected photovoltaic power generation system.…”

In order to ensure the performance and safety of photovoltaic grid connected inverter, based on hardware in the loop simulation technology, the design and implementation of photovoltaic grid connected inverter simulation and test platform are discussed. The system structure, principle and main functions of the platform are introduced. The simulation and test platform is composed of simulation and monitoring computer, simulation and measurement interface device, programmable power supply and test instruments. In the platform, the programmable DC power supply, the programmable AC power supply and RLC load is used to simulate the characteristics of solar panels, power grid and load respectively. The test process is controlled by LabWindows/CVI software interface, and the test data collection is completed through power quality analyser, power analyser, oscilloscope and simulation and measurement interface device. The simulation test software completes the data analysis and realizes the full-automatic detection of the grid connected inverter. The established hardware in the loop simulation test platform of photovoltaic grid connected inverter has the ability to conduct comprehensive test and detection of photovoltaic grid connected system, which can be used to verify and evaluate the photovoltaic inverter before it is connected to the power grid.
