By nature, humans are social creatures and thrive in urban spaces that foster social connections. Cities are essential to sustainable development since they are the center of economic development. They interact extensively with surrounding and with the rest of the world. The sustainable city concept focuses on improving the conditions of the urban areas in order to create healthy, pleasant, livable, inclusive, safe, and resilient cities where residents want to live and work. This chapter provides an introduction on sustainable cities.

Right hand grip rule is perfect for Direct current DC but what about alternative current AC Alternating current AC is an electric current that periodically reverses its direction, so does magnetic field direction changes periodically, in contrast to direct current DC which only flows in a single direction which cannot change sporadically, so does magnetic field direction does not affect. So, rule need to be corrected and separated for both AC and DC current. What do you think

Solar energy is the top of all renewable energy systems because of its pollution free, adaptable, long life, low maintenance cost and favoured options for sustainable development. Thus, this is used as the source of input for this model. The PV cell converts the solar energy into electrical energy. This energy is in DC form. This DC voltage is raised to the desired level with the help of boost converter dc dc converter .The boost converter is driven with the help of MOSFET. The boosted DC voltage is fed to the PWM inverter which converts the dc input into ac output. And finally, the output is given to the load. The proposed inverter system converts DC power into single phase AC power efficiently without using transformers and batteries. In this, the simulation results of a transformer less single phase inverter which uses a photovoltaic array as the input are shown. An inverter with DC link is designed for conversion of DC input into AC supply. The simulation is carried out with the help of MATLAB simulation software. The harmonic distortion is found to be 2.73 in the FFT analysis.

AC and DC supplies are ruling in this present electricity world. Involvement of both AC and DC supply can be seen from small circuits to big giant machineries. But is there conductor separation needed for both distinguish supply forms Are we wasting time, money and materials by using same conductors for both dissimilar supplies In my opinion, it is the right time to take decision to separate conductors for both rulers.

Due to the depletion of fossil fuels, coal, and oil, traditional electricity generation has a difficult task for utilities. A cheaper and more efficient method of doing this is required. A different source is required to fulfill the consumers power requirements. The alternate source should be sustainable and capable of meeting the consumers requirements. The integration of renewable energy into the grid is a useful way to fulfill demand. Renewable energy integration confronts three major problems frequency variation, power quality concerns, and power system instability. The following problems were of critical importance. An analytic hierarchy approach based expert system is utilized to identify and categorize power quality incidents. Before, it could sense things like sag, swell, transients, harmonics, interrupts, and flickers. An error free event classification system has been suggested. Simplified procedure allows for improved detection and categorization of power quality incidents. an investigation of power quality incidents and their mitigation using unified power quality conditioners UPQC An Adaptive Neuro Fuzzy Inference System ANFIS is used to minimize various power quality issues. Integrating renewable energy sources efficiently minimizes the environmental impact. The suggested method provides a solution to voltage unbalances and lowers overall harmonic distortion at the point of common coupling PCC . The addition of an ANFIS controlled DVR is used to reduce voltage irregularities caused by integrating renewable energy sources and faults in the transmission line. An artificial fault was added to power quality events with the goal of making use of renewable energy. To minimize the adverse effects of power quality incidents, the ANFIS controlled DVR proposal is in place. ANFIS controlled DVR is contrasted to a traditional technique of surveillance. Distributed static compensator D STATCOM is used to prevent voltage flickers, and total harmonic distortion, caused by nonlinear loads. D STATCOM is suggested to use three control methods Instantaneous power theory, Synchronous vector PI Control, and Harmonic elimination. Under extreme load circumstances, the D efficacy STATCOMs is evaluated. The suggested expert system and the bespoke power devices will be analyzed and discussed using various control techniques.

In the field of renewable energy, conversion of wind energy has become a point of major interest to the researcher. Converters are no more a small part of the wind energy system WES due to the development of generators in the WES and advancement in applications of power electronics in the WES. This paper presents a review of different topologies of converts used in the extraction of energy from wind using various generators and their combination with different converter topologies. Control scheme complexity, cost, the power consumed, and efficiency are the points considered for the comparison of converters-generator combination schemes.
