Impact of Different Types of New Energy Access on Microgrid Frequency
In order to build a new energy system and a new power system with new energy as the main body, different types of new energy have joined the power system, and the influence of the addition of a high proportion of new energy on the power system has become increasingly apparent. Based on the era background of national efforts to develop new energy, combined with the location advantages of small hydropower and wind power in the mountainous area of Guangdong province, using theory, simulation and other research methods, the frequency variation law of multi-energy complementary microgrid island composed of different kinds of new energy such as photovoltaic, wind power, small hydropower was studied in the initial stage. Firstly, the variation of the amplitude and frequency of small hydropower, wind power and photovoltaic power generation as separate distributed energy sources were respectively connected to the microgrid island operation. It was found that only the photovoltaic microgrid had better island operation stability. Then, the influence of the addition of small hydropower and photovoltaic on the amplitude and frequency change of wind power microgrid in the initial island was discussed. It was found that photovoltaic had a supporting effect on the whole working condition of wind power microgrid, while small hydropower had a greater supporting effect under specific working conditions. Finally, the influence of amplitude and frequency changes in the initial phase of the wind-light-water multi-energy complementary microgrid islanding was analyzed. The results showed that the wind-light-water multi-energy new energy had better operation stability under a certain ratio.
