Abstract

In contemporary scenario, electric power companies have observed upsurge in penetration level of tidal power plants (TPPs) in the traditional electric power system framework. However, the tidal turbines offer less frequency assistance due to their lesser rotor mass. Hence, TPPs may be collaborated with conventional units like diesel engine generator (DEG) to confirm system frequency stability in multi-area micro-grid system. The DEG comprises of primary and proportional integral derivative (PID) secondary frequency controls. However, in TPPs, to advance the system frequency regulation, deloading control approach is suggested and a cascade fuzzy fractional order PID-ID with derivative filter (CFFOPID-IDF) droop controller is suggested in place of the conventional non-cascade controller droop in the deloaded region. The suggested controller gains are fetched exploiting Salps swarm algorithm. For further enhancement of the dynamic responses, a precise high voltage direct current (AHVDC) link with the inertia emulation-based control (INEC) scheme is adopted, which allows the utilization of the gathered energy from the capacitance of the HVDC interface for frequency regulation. It provides better results compared to conventional AC tie line interface having less undershoot (34 %/20.63 %/43.75 %) and settling time (20.45 %/59.09 %/16.83 %) for variation in area-1 frequency/area-2 frequency/tie line power, respectively. The recommended control scheme is evidenced superior over numerous existing control techniques and provides least cost function in contrast to other control techniques. Additionally, it offers a highly stable performance under variable load conditions.

使用高压直流链路的基于 SSA 的新型 CFFOPID 跌落脱载潮汐涡轮机控制器
在现代情况下,电力公司注意到潮汐发电站(TPP)在传统电力系统框架中的渗透率急剧上升。然而,潮汐涡轮机由于转子质量较小,提供的频率辅助较少。因此,潮汐发电站可与柴油发动机发电机(DEG)等传统装置合作,以确保多区域微电网系统中的系统频率稳定。柴油发动机发电机由初级频率控制和比例积分导数(PID)次级频率控制组成。然而,在 TPP 中,为了推进系统频率调节,建议采用脱扣控制方法,并建议采用带导数滤波器(CFFOPID-IDF)的级联模糊分数阶 PID-ID 降压控制器来替代脱扣区域的传统非级联控制器降压。建议的控制器增益是利用 Salps 蜂群算法获得的。为进一步增强动态响应,采用了基于惯性仿真控制(INEC)方案的精确高压直流(AHVDC)链路,该方案允许利用高压直流接口电容聚集的能量进行频率调节。与传统的交流连接线接口相比,该方案具有更好的效果,在区域-1 频率/区域-2 频率/连接线功率变化时,下冲(34 %/20.63 %/43.75 %)和稳定时间(20.45 %/59.09 %/16.83 %)分别更短。与其他控制技术相比,推荐的控制方案优于众多现有控制技术,并提供了最低成本函数。此外,它还能在多变负载条件下提供高度稳定的性能。
