While the Government wants to cut down on the red tape and inefficiency associated with the lackadaisical bureaucracy, the new amendments significantly compromise on the basic principles of environmental conservation. This essay, while exploring the need for the new laws with regards to India's growing economic aspiration, also discusses why messing around with the environment is not a wise idea. The social and moral aspects of changing environmental laws, which actually accelerates environmental degradation is also looked at. This essay concludes that economic growth by compromising with the nature is not sustainable in the long term and that this policy must have a relook. Environment or Economy? This has been the million-dollar question for most modern governments across the world. The new EIA 2020 Notification rekindled the question in India.

Monitoring the generation and consumption is imperative in order to properly plan the operation as well as the installation of additional capacity. Low-cost remote monitoring of a standalone solar farm through a Raspberry Pi is proposed in this paper. RS485 is used for data transfer between the inverter and the Raspberry Pi. Remote data monitoring is then achieved by pushing the data into the cloud from the Raspberry Pi. Real-time information is made accessible which will help in preventive maintenance, fault detection and also generate a database to aid in forecasting. This IoT based solution is suitable for solar installations in remote and inaccessible areas where regular access is inconvenient. The total number of units of power generated in a day can be calculated from which an estimate can be made about the number of units generated. From this, the financial savings that can be ma...

All consumers expect Electrical energy with high power quality. Most of the commercial and industrial loads are inductive in nature and need power electronic circuits/ controllers to get smooth control of the equipment. This, in turn, leads to the injection of harmonics into the system, hence the power quality is affected. The above problem needs to be addressed and eliminated. In this paper, a shunt active power filter is used to mitigate the harmonics. Id-Iq control is used to analyse the performance of the filter and is simulated using MATLAB software. The MPPT controller is used to improving the power quality of the system.

A modified H Bridge converter utilizes a reduced number of switches for the same level output as compared to the conventional H-Bridge configuration. The lower number of switches will result in reduced switching losses, installation cost and converter cost. MATLAB/SIMULINK software is used for simulation of the different configurations used for the comparison. R and RL type of load are used and the corresponding voltage waveform is analyzed for its harmonic content. It can be seen from the results obtained that the Total Harmonic Distortion (THD) in the modified and conventional 7 level configuration is less than that of the 5 level inverter configurations.

Distributed generation is an important part of a decentralised grid. This approach employs several small-scale technologies to produce electrical energy close to the end users or consumers. The higher reliability of these systems proves to be of advantage when compared to traditional generation systems. Multi-Input Converters (MICs) perform a decisive function in Distributed Energy Resources (DERs). Making use of such MICs prove to be beneficial in terms of size, cost, number of components used, efficiency and reliability as compared to using several independent converters. This thesis proposes a double input DC-DC converter which makes use of a quasi Y-source converter in tandem with a boost converter. The quasi Y-source converter has the advantage of having a very high gain for low duty cycles. The associated operating modes are analysed and the operation of the MIC is verified using simulation result. A hardware prototype is built for large signal analysis in open loop. Different loads are applied and the efficiency of the MIC as a whole as well as the load sharing between the different sources is investigated.
A Financial Feasibility Analysis of Hydrogen in Microgrids

There is also a significant load which can be supplied with DC power. This has stimulated research in DC microgrids. The futuristic technology trend is the role of Hydrogen in microgrids as storage, in fuel cell and for mobility applications. However, a microgrid comprising of hydrogen necessitates a robust financial analysis. This paper deals with the financial modelling of the hydrogen in a microgrid. The optimization-based planning of a DC microgrid system which uses solar, hydrogen is proposed. Various economic factors like Net Present Cost, Operational Cost, Initial Capital and the Cost of Energy Unit are calculated for various topologies. The financial analytical methodology discussed can also be broadly used to design cost-effective microgrid architecture.
