Abstract: In this Paper, Fraction Order (FO) PI controller is tested in order to find the optimized gains for Automatic Generation Control (AGC) controller by Particle Swarm Optimization (PSO) algorithm to represent the Simplified Egyptian Power System (SEPS) to achieve the development of power grid for the sustainable growth of Egypt. The mission of AGC is to return primary frequency regulation capability, bring back the frequency to its predefined set point in addition to reduce power fluctuation due to unplanned tie-line power flows among nearby control zones. The suggested controller is built using actual statistical records of SEPS for minimum and maximum loading situations of the SEPS in Winter and Summer of 2019-2020. The strength of the proposed controller is illustrated by implement the suggested controller and verify the outcomes of trip of the biggest generation unit in this Simplified Egyptian Power System (SEPS) on the grid frequency. The gains of fractional order FO-PI controller parameters such as proportional, integral, order of integrator (λ) are elevated by different Particle Swarm Optimization (PSO) and compared with another conventional supplementary Proportional Integral (PI) based on PSO also. The results display that the suggested FO-PI controller-built on PSO provides finest dynamic performance for a step load variation. The used software for gaining the results is MATLAB-Simulink.

Abstract: The solid waste landfill in Zhenjiang New Area is located at the quarry entrance in the south wing of the beidingmountain of Zhenjiang New Area. Continuous heavy rainfall leads to a sharp rise in the groundwater level, causing swelling and damage to the side wall of the waterproof curtain on the east side of the foundation pit of the landfill site. As a result, the lower water level in the interior of the landfill site rises rapidly, resulting in the flooding of the landfill site and the destruction of the waterproof curtain on the east side of the foundation pit. Therefore, it is of great significance to analyze and evaluate the groundwater pollution in the study area. The main research methods are to investigate the regional hydrogeological conditions in detail and fully analyze the transport channel of groundwater pollutants in the study area. Two modules of Modflow and MT3D in GMS are used to establish groundwater flow model and solute transport model, and nitrate is selected as the sensitive factor to simulate and predict the transport law of groundwater pollutants. In the model, the pollutant leakage is 1% and 2% of the total sewage, and the migration rule, pollution range and concentration distribution of residual pollutants within 1500 days after the pollution source is cut off and the pollutant leakage continues for 180 days are simulated. According to the simulation prediction, the pollutant migrates slowly in groundwater. After the pollution source is cut off, the pollution area increases first and then decreases. The farthest migration of the pollutant is 281m, and the concentration is less than 20mg/L.
