Power quality problems in the distribution system can sometimes lead to unbalanced and uncontrolled conditions during operation. This situation can be overcome by estimating the parameters of the distribution system, thus solving the problem of load distribution. The presence of harmonic loads in the distribution system complicates the operation of the system and requires new algorithms to obtain a specific solution rather than an approximate solution. Taking all these aspects into account, this paper presents a new methodology based on decoupling by formulating intrinsic and mutual impedance networks and mathematical modeling of these networks along with ancillary methodology. This methodology is applied to solve an unbalanced distribution system with 13 nodes and 11 harmonic loads connected in different parts of the system. The obtained results are confirmed by the existing literature methods.

India is a dynamically developing country in which 60% to 65% of the industry consumes electricity. Many Indian firms are improving their technology, so the demand and supply of electricity is growing. With the help of energy audits, it can reduce the gap between energy demand and supply as much as possible, which is good for all sectors and it can manage the maximum demand for energy in companies and improve the power factor by reducing energy losses and improving energy efficiency. This paper is a preliminary investigation by Vandana Global Limited, Raipur. Comprehensive load study of industries with 7000 KVA monthly contract demand, new loads have been introduced in this industry, highlighting the need for significant energy conservation measures. To evaluate the savings, a full energy audit must be carried out. After energy analysis of the monthly electricity bill, the four-month average power factor is 0.92, therefore the grid power factor can be increased as inductive loads are fewer. It can use the automatic reactive control panel to improving to the grid power factor by adjusting the required reactive power from the grid connected alternator. The system is effective due to cost savings, return on investment and profit. Time of Day (TOD) and conserve energy meter readings were used to measure demand control. Energy Audit energy efficiency solutions reduce energy waste and energy costs. In general, special attention was paid to reduce demand losses and energy costs. This paper recommends using genuine energy in the right place and organizing the use of energy through an energy audit.
印度是一个充满活力的发展中国家，其中60%至65%的工业消耗电力。许多印度公司正在改进他们的技术，因此电力的需求和供应都在增长。在能源审计的帮助下，它可以尽可能地减少能源需求和供应之间的差距，这对所有部门都有好处，它可以管理公司对能源的最大需求，并通过减少能源损失和提高能源效率来改善功率因数。这篇论文是由Vandana Global Limited, Raipur进行的初步调查。综合负荷研究7000千伏安月合同需求行业，新负荷已在该行业引入，突出需要显著的节能措施。为了评估节省的费用，必须进行全面的能源审计。经月度电费分析，4个月平均功率因数为0.92，因此随着感性负荷的减少，电网功率因数可以增加。利用自动无功控制面板通过调节并网交流发电机所需的无功功率来提高并网功率因数。由于节省成本，投资回报和利润，该系统是有效的。每日时间(TOD)和节约能源表读数用于测量需求控制。能源审计能源效率解决方案减少能源浪费和能源成本。总的来说，特别注意减少需求损失和能源成本。本文建议在正确的地方使用真正的能源，并通过能源审计组织使用能源。

Detailed modeling of rapid charging Electric Vehicle (EV) stations connected to a hybrid grid-Renewable Energy Systems (RES), such as solar, mini-hydro, and wind, has been proposed. This assists in maximizing profit and lowering grid energy consumption. Since Photovoltaic (PV) systems exhibit several peaks under partial shading conditions; it is very difficult to track the global maximum point. Therefore, a broad search is needed to solve this nonlinear problem. Due to the variety of solutions, GA is preferred for solar MPPT. In comparison to the Genetic Algorithm (GA) and Maximum Power Point Tracking (MPPT) technique, the economic considerations obtained optimizes profit. It is also obvious that the proposed strategy lowers the grid's influence on the system network by capping the amount of electricity that may be exchanged between the system network and the grid. The voltage and current of PV array with GA method and GA MPPT technique results on the utility grid respectively.

A significant amount of interest from the scientific community has been focused on Direct Current (DC) microgrids in recent years, as a direct result of the proliferation of appliances that run on DC power. Nevertheless, the acceptability of DC microgrids by power utilities is still restricted owing to the challenges connected with the construction of a dependable protection system. This is because obtaining dependable protection for DC microgrids might be difficult due to the large size of DC fault current, its quick rate of rise, and the lack of zero crossing. In addition, the intermittent nature of the power produced by non-traditional distributed generators necessitates adaptability in response to a wide range of climatic circumstances. The method used in this study to solve the problems outlined above is developing an Ensemble of Decision Tree-based protection solutions for a multi-terminal DC microgrid. The plan developed accommodates the intermittent nature of renewable energy sources. It only uses information that is local to the current and voltage signals, which allows it to execute the duties of fault detection and classification, and prevents the disadvantages associated with communication networks, such as data loss and delay.

Energy consumption has increased dramatically and steps towards the energy efficiency goal and emphasizes that an energy audit is an ongoing operation. It addresses the feasible activities, such as how to conserve and efficiently use our limited resources, and identifies how it reduces the capacity and how to translate these efforts into reality. A plant or facility may undergo an energy audit to determine energy consumption and energy conservation practices, as well as where and how energy is used. Improved procedures, better tools, and more efficient equipment can help to save energy.
