[IEEE 2019 International Power System Conference (PSC) - Tehran, Iran (2019.12.9-2019.12.11)] 2019 International Power System Conference (PSC) - Optimal model predictive control of photovoltaic plants for frequency regulation in an interconnected power system
摘要： Due to growing development of photovoltaic (PV) plants in power systems, they are capable to provide ancillary service for frequency regulation. PV plants provide the required reserve of generation through operating below the maximum power point tracking. This paper proposes a model predictive control (MPC)-based approach for power control of PV plants contributing towards load frequency control (LFC). In MPC, the control signals are provided through optimizing a cost function which includes the plant model as well as current and past signals of the system. Since the successful performance of the controller depends on the well-adjusting of its weights, the weights of the controller are regulated by sine cosine algorithm to earn an optimal performance. Comprehensive discussions are presented on a three-area interconnected power system. The effectiveness of the proposed scheme is demonstrated through case studies and thereby relevant conclusions are drawn.

[IEEE 2020 First International Conference on Power, Control and Computing Technologies (ICPC2T) - Raipur, India (2020.1.3-2020.1.5)] 2020 First International Conference on Power, Control and Computing Technologies (ICPC2T) - Load Frequency Control of Solar Photovoltaic/Wind/Biogas/Biodiesel Generator Based Isolated Microgrid Using Harris Hawks Optimization
摘要： This study proposes an approximate mathematical model of an isolated microgrid consisting of solar photovoltaic, wind turbine, biogas, biodiesel generators, flywheel and battery storage system for load frequency analysis. A proportional-integral(PI) cascaded through tilt-integral-derivative with derivative filter(TIDF) controller named PI-TIDF is suggested for load frequency regulation of the microgrid. To tune controller parameters a newly proposed harris hawks optimization(HHO) is applied utilizing ITAE fitness function. The superiority of the HHO is established by comparison with other techniques such as GOA, CSA and GA. Then using HHO, comparison between PIDF, TIDF and PI-TIDF is done for load frequency control. From frequency response, it is found that HHO tuned PI-TIDF is having better performance compared to TIDF and PIDF. Lastly, the ability of the suggested technique is examined by changing the frequency and magnitude of disturbances. In the changed disturbance case, proposed control scheme is proved to have satisfactory performance without retuning the controller parameters.

A Novel Modified Robust Load Frequency Control for Mass-Less Inertia Photovoltaics Penetrations via Hybrid PSO-WOA Approach
摘要： The high penetrations of distributed energy resources (DERs) leads to severe problems such as reducing system inertia and increasing the frequency deviations from the nominal value. The main target of this study is to enable modern photovoltaics (PVs) with large penetration amounts to participate effectively in the load frequency control in the interconnected power systems, in which frequency and tie-line power sharing deviations exist. In this research, a model for the solar PV is developed to help study the heavy penetration of the solar PVs within interconnected power systems. Secondly, a time domain objective function based on the norm of the area control error is formulated. Thirdly, in order to tune the PI controllers, a combined meta-heuristic algorithm based on particle swarm optimization and whale optimization algorithm (PSO-WOA) is developed and compared with the individual PSO and WOA controllers. From the studied scenarios, the developed combined scheme outperforms the other algorithms in terms of system performance indices. Therefore, the developed PSO-WOA approach is plausible and straightforward to solve many engineering problems as it benefits from the exploitation characteristics of the conventional PSO and the exploration features of the WOA.

A hybrid shuffled frog‐leaping and pattern search algorithm for load frequency controller design of a two‐area system composing of PV grid and thermal generator
摘要： The shuffled frog-leaping algorithm (SFLA) is a nature-inspired metaheuristic swarm-based optimization algorithm, which mimics the social behavior of memetics. The SFLA comprises an arrangement of communicating virtual population of frogs divided into various memeplexes. Many attempts have been made to find the variant of the SFLA that performs better on a variety of optimization tasks by making the original SFLA more complex. This paper proposes the hybrid approach by combining the SFLA algorithm with a pattern search algorithm, which improves the original technique named as the hybrid shuffled frog-leaping and pattern search algorithm (hSFLA-PS). The superiority of the proposed hybrid algorithm over the original SFLA in terms of implementation time and solution quality is compared by taking several benchmark test functions. In the next step, the real application of the proposed hybrid approach in the engineering field is done by designing a proportional-integral-derivative (PID) controller for frequency regulation of a two-area power system that is composed of a photovoltaic (PV) grid and a thermal generator. It is observed that the hSFLA-PS–based PID controller is more effective for the load frequency control compared with conventional controllers tuned with genetic algorithm (GA) and firefly algorithm (FA).
