“…The major purpose of M&V is maximizing the accuracy of energy savings, optimizing financial efficiency projects, increasing the public understanding of energy management, and addressing the significance of emission-reduction credit [170]. Part of the M&V methodologies to be followed is fitting and maintenance of meter calibration, collection and analysis of data and justifiable results, and verification of reports [171]. The International Performance Measurement & Verification Protocol (IPMVP) defines four different M&V options: partially measured retrofit isolation (A), retrofit isolation (B), whole facility (C), and calibrated simulation (D) [172].…”

The increase in energy consumption, environmental pollution issues, and low-carbon agenda has grown the research area of demand side management (DSM). DSM programs provide feasible solutions and significantly enhance the efficiency and sustainability of electrical distribution systems. This paper classifies and discusses the broad definition of DSM based on the comprehensive literature study considering demand response and energy efficiency. The implementation of Artificial Intelligence algorithms in DSM applications has been employed in many studies to help researchers make optimal decisions and achieve predictions by analyzing the massive amount of historical data. Owing to its simplicity and consistent performance in fast convergence time, Particle Swarm Optimization (PSO) is widely used as a part of the swarm AI algorithm and has become a prominent technique in the optimization process to exploit the full benefit of the demand-side program. The variants of PSO have been developed to overcome the limitations of the original PSO and solve the high complexity and uncertainty in the DSM optimization process. The proposed PSO-based algorithm can optimize consumers' consumption curves, reducing the peak demand and hence minimizing the electricity cost when integrated with the DR programs or EE measures. The research works of the PSO algorithm in DSM have seen an increasing trend in the past decade. Therefore, this paper reviewed the application of the PSO-based algorithm in DSM fields with some constraints and discussed the challenges from the previous work. The potential for new opportunities is identified so that PSO methods can be developed for future research.INDEX TERMS Demand side management (DSM), demand response (DR), energy efficiency (EE), metaheuristic algorithms, particle swarm optimization (PSO), swarm intelligence.

“…In addition, in 2020, GHG emissions were reduced by 2.71 (t CO 2 ) as a result of energy savings. Ultimately, energy efficiency was achieved, which reduced residents' doubts about the long-term benefits of using energy efficiency tools [33]. Investing in solar panels on roofs could also reduce the problem of the energy crisis due to the high potential of solar energy and the low prices of the PV system, which shorten the payback period [34].…”

Solar energy is a source of energy that can meet a significant part of the demand for heat and electricity. However, its acquisition is associated with high variability both during the year and on individual days. The construction of installations due to changes in tariff systems, investment costs and subsidy programs raises doubts as to their profitability. The aim of this study was to assess the profitability of photovoltaic investments for households, considering public financial support. This study used RetScreen Expert software 8.1.2.13 to perform the entire analysis and performance cost, risk and sensitivity simulations. Climate data were imported from ground monitoring stations or from NASA global satellite or analytical data. The conducted research showed the profitability of investments in photovoltaics, even without state support. Differences between regions were insignificant. However, the support system has changed, extending the period of return on investment.

“…These indicators are explained in detail in the following subsections. The initial economic parameters, like the growth rate of energy cost, the rate of inflation, plus the cost of the main components of the PV power plant, are taken following the data given in Table II [13,14]. a) Internal Rate of Return (IRR): Through IRR, companies can learn the feasibility of investment of the projects in the long term as it is one of the methods of capital budgeting.…”

The construction of photovoltaic power plants (PVPPs) in the right place is an important task when planning the development of the power system and choosing investors. In this paper, the technical, environmental, the economic feasibility of installing a 50kW solar power plant in different places in the New Valley Governorate in Egypt has been presented using RETScreen Expert software. The input data used in the current study are obtained from the database of the Surface Meteorology and Solar Energy Dataset of NASA. In general, five sites for the construction of 50 kW power stations were assessed which represent the five administrative regions of the New Vally governorate. The study is based on annual electricity production, greenhouse gas (GHG) emissions, and financial analysis. With the proposed PV power plant, up to 100 MWh of electricity can be produced and a minimum of 43.3 tons of GHG emission can be prevented from the exhaust into the local atmosphere annually The obtained results from the RETScreen program proved the viability of installing the proposed 50kW photovoltaic power plant in any of the proposed locations. This study could give a piece of important information and feedback that can be utilized as a database for upcoming investments in the photovoltaic generation projects in Egypt.
