About this book

This book evaluates a number of serious technical challenges related to the integration of renewable energy sources into the power grid using the DIgSILENT PowerFactory power system simulation software package. It provides a fresh perspective on analyzing power systems according to renewable energy sources and how they affect power system performance in various situations. The book examines load flow, short-circuit, RMS simulation, power quality, and system reliability in the presence of renewable energy sources, and presents readers with the tools needed for modeling, simulation, and analysis for network planning. The book is a valuable resource for researchers, engineers, and students working to solve power system problems in the presence of renewable energy sources in power system operations and utilities.

Chapter 1. Introduction to Techno-Economic Assessment of Renewable Energy Sources
Abstract
Over the past two decades, the International Energy Agency (IEA) has focused on encouraging various countries to invest in multi-source power generation systems, including renewable energy sources (RES) and associated power grids. Accordingly, it is imperative that all decision-makers and national experts master the technical and economic requirements regarding the integration of renewable sources into power systems. In general, the assessment and feasibility studies of renewable energy installations can be investigated from different perspectives. Hence, this chapter presents the basic steps required to evaluate RES from technical and economical points of view.

Chapter 2. Introducing Basic Tools in DIgSILENT PoweFactory
Abstract
DIgSILENT PowerFactory is one of the most powerful software to technical analysis of the power grids and also determine the optimal operation of each element in the electrical network. This chapter presents the required tips for modeling key elements of the power grid in PowerFactory. It can be used to simulate and analyze different studies in the power grid.

Chapter 3. Modeling and Optimal Operation of Renewable Energy Sources in DIgSILENT PoweFactory
Abstract
This chapter presents the instruction on how to model renewable energy sources (RES) within the framework of power systems. Different stochastic models will be discussed, such as Weibull distribution function, time series, and generation adequacy in DIgSILENT PowerFactory. The modeling of RES is performed based on some predictions, including ambient temperature, solar radiation, and wind speed.

Chapter 4. Power Quality and Harmonics Analysis in the Presence of Renewable Energy Sources
Abstract
This chapter explains how to determine power quality indices by DIgSILENT PowerFactory in the presence of renewable energy sources. In PowerFactory software, Harmonic Load Flow Analysis and Impedance Frequency Analysis can be used to analyze power grids in terms of power quality. The outputs of these analyses show various indicators of the system’s power quality especially harmonic distortion (HD) and total harmonic distortion (THD).

Chapter 5. Electrical Challenges Associated with Integrating Renewable Energy Sources into Power Grids
Abstract
This chapter presents a comprehensive analysis of the effect of renewable energy sources (RES) in the technical parameters of the power system. In addition, several standard case studies presented to compare the impact of RES in various operation modes with conventional generating units and the battery energy storage system (BESS). It should be noted that the main focus of this chapter is to examine the electrical challenges resulting from the misuse of RES during the operation of power systems. Therefore, it is assumed that the optimal scheduling problem considering RES was performed on the desired test system by default. PowerFactory provides very useful packages for the system operator to investigate the status of the power grid in coordination with various renewable sources technologies, and perform the required technical analysis. Required operation tools to incorporate renewable sources in smart power grids include:
  • Power flow analysis with low to high penetration of RES.
  • Short-circuit studies and contingency analysis with stochastic models that capture the uncertainty of RES.
  • Short-term rescheduling according to network performance after performing various simulations in the presence of RES as well as BESS.

Chapter 6. Reliability Assessment in the Presence of Renewable Energy Sources
Abstract
This chapter presents the instruction on how to evaluate the reliability indices in the presence of renewable energy sources (RES) in DIgSILENT PowerFactory. In this chapter, the reliability issue is examined from two perspectives. In the first step, the impacts of RES on the improvement of various reliability indices are investigated. In the next step, how to calculate the fundamental reliability indices in the renewable power generation sector, such as loss of load probability (LOLP), is presented. To this end, different case studies are analyzed and the various reliability indices are assessed on the standard test system.

Chapter 7. Evaluation of the Real Grid-Connected Photovoltaic Systems in Iran
Abstract
The main goal of this chapter is to investigate the effects of the real grid-connected photovoltaic (PV) systems on the distribution network. The networks used in previous chapters were ideal, so the impacts of renewable energy sources (RES) on improving the technical aspects of those networks were not well demonstrated. Therefore, a real test system, which is part of the East Azerbaijan distribution network in Iran, has been used to overcome this issue. The introduced tools in previous chapters have been used to perform the required analyses for evaluating the performance of the power grid in the presence of the real grid-connected PV systems. In this chapter, all the required steps to conduct a comprehensive technical study for grid-connected renewable energy systems are fully described.
