In the global pursuit of carbon neutrality and sustainable development, the new energy sector—encompassing wind power, solar photovoltaic (PV) energy, hydropower, and energy storage systems—has emerged as a cornerstone of the transition from fossil fuels to clean energy sources. However, the inherent characteristics of new energy generation, such as intermittency, volatility, and non - linearity, pose significant challenges to the stability, efficiency, and reliability of power grids. This is where reactors, as essential power electronic components, play an indispensable role in safeguarding the smooth integration and operation of new energy systems.

One of the primary challenges in new energy applications is the issue of power quality, particularly voltage fluctuations and harmonics. Wind power generation, for instance, is highly dependent on wind speed, leading to frequent changes in output power. These fluctuations can cause voltage sags or swells in the grid, which not only affect the normal operation of other connected loads but also reduce the lifespan of power equipment. Reactors, especially series reactors, effectively mitigate voltage fluctuations by suppressing the rate of change of current. They act as a "buffer" in the power system, absorbing sudden current surges and stabilizing the voltage level, ensuring that the power fed into the grid remains within acceptable limits.

Similarly, solar PV systems face challenges related to harmonic distortion. The use of power electronic converters in PV inverters, which convert direct current (DC) generated by solar panels into alternating current (AC) for grid connection, often introduces non - linear currents. These non - linear currents give rise to harmonics in the grid, distorting the sinusoidal waveform of voltage and current. Harmonics can lead to overheating of transformers, motors, and cables, increase power losses, and even interfere with the operation of sensitive electronic equipment. Shunt reactors and harmonic filters (incorporating specialized reactors) are widely employed to address this issue. Shunt reactors help compensate for reactive power, improving the power factor and reducing harmonic currents, while harmonic filters are designed to absorb specific harmonic frequencies, ensuring that the power injected into the grid meets strict harmonic standards.

Another critical aspect where reactors contribute to new energy systems is in enhancing grid stability during fault conditions. When a short - circuit fault occurs in the grid, the sudden increase in fault current can cause severe damage to power equipment, including generators, transformers, and inverters. Reactors, such as current - limiting reactors, are installed in series with the power lines or equipment to limit the magnitude of the fault current. By restricting the fault current to a safe level, reactors protect the equipment from damage and prevent the fault from spreading to other parts of the grid, thereby maintaining the overall stability of the power system. This is particularly crucial for large - scale new energy farms, where a single fault can have a significant impact on the entire grid's operation.

In addition to power quality and grid stability, reactors also play a vital role in energy storage systems, which are essential for addressing the intermittency of wind and solar energy. Energy storage systems, such as battery energy storage systems (BESS), rely on power converters to charge and discharge batteries. During the charging and discharging processes, the converters can generate voltage and current ripples, which can affect the performance and lifespan of the batteries. Reactors are used in the converter circuits to smooth out these ripples, ensuring a stable DC voltage and current supply to the batteries. This not only improves the efficiency of the energy storage system but also extends the service life of the batteries, reducing the overall cost of the system.

Furthermore, reactors are instrumental in the integration of distributed new energy resources into the distribution grid. Distributed generation, such as rooftop solar PV systems, is often connected to the low - voltage distribution grid. However, the intermittent output of these distributed resources can cause voltage fluctuations and overloads in the distribution grid, especially during peak demand periods. Reactors, when used in combination with other power quality devices, can help regulate the voltage and current in the distribution grid, ensuring that the distributed new energy resources are integrated seamlessly without compromising the grid's reliability.
