Abstract

With the advancements of photovoltaic panels Solar power plants extend their grip further in the power system every day. It is necessary that these new power plants work together with classic power plants. In this paper the simultaneous operation of a solar power plant with a steam power plant in a power system has been considered. The solar power plant operates with incremental conductance maximum power point tracking (IncCon MPPT) with direct control which is implemented through a boost converter. The inverter of solar power plant is manipulated to perform active power filtering in addition to converting DC power to AC. A d-q reference frame controller is used to perform the active power filtering. The steam power plant is also uses a PSS to stabilize the power system and damp power transients. A metaheuristic method called smart line search teaching learning based optimization (SLS-TLBO) is used to optimize the PSS parameter. In this paper, it is shown that the simultaneous operation of solar power plant can enhance the performance of the power system.

蒸汽与太阳能并网发电系统的稳定性及功率因数改进

随着光伏板技术的进步，太阳能电站在电力系统中的地位日益扩大。这些新电厂必须与传统电厂协同工作。本文研究了一个电力系统中太阳能发电厂与蒸汽发电厂同时运行的问题。太阳能发电厂采用增量电导最大功率点跟踪(incon MPPT)运行，通过升压转换器实现直接控制。控制太阳能发电厂逆变器在将直流电源转换为交流电源的同时进行有源滤波，采用d-q参考框架控制器进行有源滤波。蒸汽发电厂还使用PSS来稳定电力系统和抑制电力暂态。采用基于智能线搜索教学学习的元启发式优化方法(SLS-TLBO)优化PSS参数。本文的研究表明，太阳能发电厂同时运行可以提高电力系统的性能。
