Soft Computing Methodologies for Hybrid Renewable Energy Sources in Smart Grid Adaptive Control Owing to the evolution of the smart grid, the emergence of hybrid renewable energy system (HRES) and the proliferation of plug-in-hybrid electric vehicles (PHEVs), the development of efficient and robust maximum power point tracking (MPPT) algorithms for renewable energy sources due to their inherent intermittent nature has overwhelmed the power industry. The HRES is a looming power generation scheme due to the plentiful availability of renewable energy sources (RESs). The renewable energy sources are intermittent in nature due to uncertain meteorological conditions. The residential and charging station loads behave in an erratic manner. In this scenario, to maintain the balancebetweengenerationanddemand, thedevelopmentofanintelligentandadaptive control algorithm has preoccupied power engineers and researchers. This research work presents the indirect adaptive tracking control of renewable energy sources in a grid-connected hybrid renewable energy system.

An adaptive Chebyshev-wavelet embedded NeuroFuzzy indirect MPPT control (ACWNF-MPPT) paradigm is proposed for variable speed wind energy conversion system (VS-WECS). An adaptive feedback linearization-based NeuroFuzzy MPPT (AFBLNF-MPPT) algorithm for a photovoltaic energy conversion system(PVECS)andanadaptiveHermite-waveletincorporatedNeuroFuzzyindirecttracking control (AHWNF) scheme for Solid Oxide Fuel Cell (SOFC) are developed. The charging infrastructure plays a vital role in the healthy and rapid development of electric vehicles industry. The charging station (CS) which consists of five different PHEVs and a battery storage system (BSS) is integrated to a grid-connected HRES having wind turbineMPPTcontrolledsubsystem, photovoltaicMPPTcontrolledsubsystemandcontrolled SOFC with electrolyzer subsystem which are characterized as renewable energy sources. Adaptive PID (AdapPID) control paradigm is used for non-renewable energy source (micro-turbine), storage system (battery and super-capacitor), grid side inverter and the charging station (CS converter, battery storage system (BSS), PHEVs). A comprehensive simulation test-bed for a grid-connected HRES is developed in Matlab/Simulink. The performance of the stated indirect adaptive control paradigms are evaluated through simulation results by comparison with conventional and intelligent control schemes. The simulation results prove the effectiveness of the proposed control paradigms.
پاکستان جیسے ملک میں پولیس کی سستی اور عدم تعاون کا مرکز عمومی طور پر حدودمقدمات ہوتے ہیں ۔ پھر ان مقدمات کا دعویٰ بہت تاخیر سے دائر ہوتا ہے ۔ پھر بہت زیادہ تاخیر سے ان مقدمات کے کیس عدالتوں میں لگتے ہیں اور بآلاخر ان مقدمات کے فیصلے بھی بہت سالوں بعد ہوتے ہیں ۔اس کی بنیادی وجہ پولیس کی سستی ، رشوت کی عادات ، وکلاء کا عدم تعاون اور ججز کی تعداد کا کم ہونا ہے۔ پاکستانی معاشرہ اس وقت جرائم کا گڑھ بن چکا ہے ۔ روزاانہ کی بنیاد پر کافی زیادہ جرائم رپورٹ بھی ہوتے ہیں اور ان کی FIR بھی درج ہو تی ہیں ۔پھر یہ مقدمات عدلیہ کے سامنے پیش ہو تے ہیں ۔ اس طرح حدود وقصاص کے مقدمات سالوں تک چلتے ہیں۔ اس کے علاوہ اداروں کے آپس میں مربوط نہ ہونے کی وجہ سے حدود وقصاص کے مقدمات کو غلط طریقے سے نمٹایا جا تا ہے۔ وقت پر انصاف نہ ملنے کی وجہ سے مظلو م اور متضرر اپنے عدالتی نظام سے اور انصاف نہ ملنے پر ریاست سے بھی بد ظن ہو جاتے ہیں ۔
Islam is the complete code of life. The Prophet (PBUH) and his companions made every effort to safeguard it. They handed it over in fully preserved form without any flaw to their true followers. However, adversaries of Islam have been trying to find faults with safety of Quran and the life of Prophet (PBUH). Orientalists are among them. Orientalists are those non-Muslim scholars, who do their research about Muslim’s beliefs, culture and values. Their purpose is to double edge. First to create doubts in the minds of Muslims regarding their religion. Secondly to marsh hated in the hearts and minds of non-believers. This is why these prejudiced scholars criticize Quran and the personal life of Prophet (PBUH). In the following discussion we have analyzed these objections in detail regarding the safeguard of the Holy Quran during the time of Muhammad (PBUH).
Geo-Politics of Pakistan-China strategic partnership are highly vital and critical for both regional and global politics. Both countries have enjoyed “all weather friendship” in last seven decades. The major reasons for strong ties of these two states are ever increasing Indo-US ties and emerging of China as economic power. With passage of time both neighbouring states have further strengthen their relationship through numerous ventures like CPEC, JF-17 Thunder and various military and economic agreements.Sino-Pakistan ties are also important for strategic balance in South Asia to counter Indo-US influence in the region. Although Pakistan has enjoyed close ties with United States but its increasing tilt towards India has forced Pakistan to look for other options and China is natural and best option for Pakistan in every aspect. Another aspect of Sino-Pakistan ties is Gwadar port which has emerged as strategically significant especially against Iranian Chahbahar port which is being developed through Indian investment. Hence, to maintain the economic, military, and strategic balance in South Asian Region, the Pakistan-China ties are not only vital but also essential. The Pakistan-India ties are also essential for the regional stability especially in context of the US-India nexus in the South Asia. Both India and USA are trying hard to tilt the geo strategic balance in their favor tackling Pakistan-China policies and strategic steps in the region i.e. Gwadar Port, China Pakistan Economic Corridor (CPEC) and presence in Indian Ocean. Although Pakistan was the front ally in War Against Terrorism with the US, but the America has shown its clear tilt towards India signing major trade, military and nuclear deals, hence Pakistan has strengthened its ties with China and further seeking strong relations with Russia and other regional states.
