Role of Renewable Energy Sources in Evaluating Technical and Economic Efficiency of Power Quality

Abstract

Due to the growing use of Renewable Energy Sources (RES) in many countries, the need for an accurate and detailed analysis from the technical and economic view point seems to be necessary. Power Quality (PQ) can also be another considerable matter that needs to be carefully evaluated. In this regards, in this article, an analytical and detailed approach is presented to evaluate the technical and economic performance of the strategy for PQ changes. In addition, an optimization-based PQ change strategy is presented to provide a distinct PQ in integrated grids with renewable generations. The proposed strategy is based on the assessment of financial losses due to changes in the quality of power and the cost estimation of various reduction approaches and repayment solutions. This approach presents various customer requirements and various levels of PQ in the power grid. In order to evaluate the performance of the proposed method, the effectiveness of the presented model has been utilised in an actual case study, and the results have been obtained and analysed. The results of the simulation provide both technical and financial advantages to obtain optimal change strategy.

Optimal Multi-Operation Energy Management in Smart Microgrids in the Presence of RESs Based on Multi-Objective Improved DE Algorithm: Cost-Emission Based Optimization

“…Using RESs and green powers, including wind and photovoltaics, can offer notable environmental advantages [1][2][3][4]. In this way, MG can act as a concept that gives an effective solution for integrating renewable DGs into the major power and energy network and offers the requirements of next generation power systems [5][6][7][8]. Overall, a MG network system consists of a number of homes, industrial, and commercial consumers, as well as DGs (essentially RESs), with a central control system, which typically uses one or more battery energy storage (ES) systems as backup [9,10].…”

Identification of Energy Efficiency Trends in the Context of the Development of Industry 4.0 Using the Polish Steel Sector as an Example

“…A systems approach to energy efficiency management in and outside the production facilities (layout, energy producer, supplier, user) is required. Essentially, this approach involves increasing the share of renewable energy in total energy consumption and improving the energy efficiency in the network of energy producers and users with a significant diversification of energy sources [29][30][31][32][33][34].…”

Power Quality and Reliability Considerations of Photovoltaic Distributed Generation

“…However, with the increasing power demand, population growth, and the increase in the life stander requirements, the electrical system must be supported by transmission line extension with the new power plants [2]. Comprehensive improvement of power system quality levels in specific areas of the electrical distribution network can have a wider application scope and provide higher overall benefits when network compensate activity is implemented at the optimum point in the distribution network level [3]. The Distributed Generator (DG) is considered as more economic and environmental aspects as compared with adding the power plants with the new remote load.…”
