摘要： This paper proposes a new fast technique, in which the slope of a photovoltaic (PV) inverter current is utilized to predict if the current is expected to exceed its rated value due to any grid faults. Two applications of this technique are demonstrated. In jurisdictions where grid codes require distributed generators (DGs) to disconnect after a fault occurrence, such as in Ontario, Canada, this technique is utilized to rapidly disconnect the PV solar system even before the inverter short circuit current actually exceeds the rated current of the inverter, thereby obviating the problem of any adverse short circuit current contribution into the grid. However, in regions where grid codes require DGs to stay connected and provide grid support, such as low-voltage ride through, this technique can be used to rapidly and autonomously transform the PV solar farm into a dynamic reactive power compensator STATCOM (termed PV-STATCOM) for providing voltage support function. In this paper, the PV-STATCOM is used to stabilize a critical induction motor load in the vicinity of the solar farm, which would have otherwise become unstable due to the grid fault. PSCAD-based simulation studies are performed on a realistic distribution network to demonstrate the effectiveness of this technique.

[IEEE 2018 International Conference on Information , Communication, Engineering and Technology (ICICET) - Pune, India (2018.8.29-2018.8.31)] 2018 International Conference on Information , Communication, Engineering and Technology (ICICET) - New Control Technique to Improve the Grid Power by Using PV-STATCOM
摘要： This paper introduces novel control method to utilize the solar plant inverter as static synchronous compensator (STATCOM) which is also called as PV-STATCOM to improve the power transmission capacity of the grid. The solar farm is ideal for the nighttime and it produces less power in morning period and late afternoon period. Therefore these are the expensive assets which are remaining unutilized during this period of 24hrs. To overcome these problems solar plant along with maximum power point tracking [MPPT] produces active power during daytime and full capacity of solar plant inverter which is not used in night period is used with help of point of common coupling [PCC] voltage controller and damping controller to improve the power transmission capacity of line and also power factor of the grid line. The inverter capacity which is left after the real power generation is used to perform the given objective. This new control technique is used to increase the grid transfer capacity for which other alternatives are used like FACT devices.

摘要： The environmental effect and need of energy have been increasing rapidly, due to this demand for renewable resources increased. One of the renewable resources Solar Photovoltaic (PV) energy is presently most popular in the environment. An inverter is a necessary part of grid-connected PV systems. This paper presents a new approach of large-scale photovoltaic solar farm inverter as STATCOM, known as PV-STATCOM, for regulation of voltage at the point of common coupling which recovers the voltage stability of the transmission line. Over daytime, the solar PV farm generates active power, but stay in idleness at the night-time. In this paper, PV-STATCOM incorporating multilevel inverter is presented. The voltage at the PCC is regulated at different loading conditions using PV-STATCOM. The entire system modeling and study are performed using MATLAB/SIMULINK.
