  • New Developments in Power System Economics


    Operation of Electrical Transmission with Nodal Pricing and Pool System

    Introduction :

    Power system consists typically of generators, transformers, transmission lines, ‎busbars, and utility equipment. Some electricity utilities were vertically integrated, generating the electrical energy, transmitting it ‎from the power plants to the load centres and distributing it to individual consumers. ‎In other cases, utility from which consumers purchased electricity was responsible only ‎for its sale and distribution in a local area. This distribution utility in turn had to purchase electrical energy from a generation and ‎transmission utility that had a monopoly over a wider geographical area.‎

    The process of unbundling of electricity was required to separate the production ‎and trading of electrical energy from the operation of this power system to minimise monopoly and ensure security of supply. Security of electricity supply can be defined as the ability of the electrical power system to provide electricity to end-users with a specified level of continuity and quality in a sustainable manner. In the Sultanate of Oman, for example, the Royal Decree (RD) No.78/2004 promulgating The Law for ‎the Regulation and Privatisation of the Electricity and Related Water Sector was issued ‎by His Majesty Sultan Qaboos bin Said in 2004. The main objective of this course is to introduce to participants the unbundling and deregulation, and power system operation taking into consideration the technical and economic constraints.

    Course Objectives :
    Presenting an overview of power system operations and control. Introducing the process of privatization and unbundling of electricity sector.‎ Presenting the current structure of electricity market in Oman.‎ Introducing the main concepts of economics those are relevant to electricity industry.‎ Introducing the different electricity market mechanisms.‎ Highlighting the importance of economic dispatch in electricity market. Illustrating the different mechanisms for handling the ancillary services in new electricity markets.‎ Demonstrating the main constraints in electricity transmission system.

    Who Should Attend :
    The short course is targeted for electrical engineers, and regulation engineers who are involved in the area of electricity supply industry or its relevant disciplines. However, the course should also be of interest to other people who wish to develop their career in managing electricity companies or interested in acquainting themselves with tools necessary to work in electricity dispatch centres or regulation authorities or generation, transmission, supply, or distribution companies.

    Course Modules and Topics :
    This is a basic skeleton of the course contents. Participants will be given detailed notes and will be trained on using DIgSILENT PowerFactory in modelling and simulation of protection devices.

    Module 1: Introduction.

    Key Players, New Electricity Industry Structures, Electrical Energy as a Commodity, Open Electrical Energy Markets, Bilateral Trading, Electricity Pools, Obtaining Balancing Resources, Interactions between Managed Spot Market and Other Markets, The Settlement Process,.

    Module 2: Operation of Electrical Energy Markets.

    The Consumer's Perspective, Retailers of Electrical Energy, The Producer's Perspective, Perfect Competition, Basic Dispatch, Piecewise Linear Cost Curves, Scheduling, Start-up Cost, Dynamic Constraints, Environmental Constraints, Other Economic Opportunities, Imperfect Competition, Perspective of Plants with Very Low Marginal Costs, Hybrid Participant's Perspective.

    Module 3: Power System Security and Ancillary Services.

    Limits on Power Transfers, Voltage Control and Reactive Support Services, Stability Services, System Restoration, Obtaining Ancillary Services, Compulsory Provision of Ancillary Services, Market for Ancillary Services, Demand-Side Provision of Ancillary Services, Buying Ancillary Services, Co-Optimization of Energy and Reserve in a Centralized Electricity Market, Allocating the Costs, Selling Ancillary Services.

    Module 4: Operation of Electrical Transmission Networks.
    Operation of Transmission Network, Physical Transmission Rights, Centralized Trading Over a Transmission Network, Centralized Trading in Two Bus System, Unconstrained Transmission, Constrained Transmission, Congestion Surplus, Centralized Trading in Three Bus System, Economic Dispatch, Nodal Prices, Merchandising Surplus, Losses in Transmission Networks, Effect of Losses on Generation Dispatch, Managing Transmission Risks in Centralized Trading System, Financial Transmission Rights, Flowgate Rights, The FTR Versus FGR Debate.

    Computer Applications :
    DIgSILENT Power Factory simulation and analysis software will be used extensively during the course. This software is the leading high-end tool for applications in generation, transmission, distribution and industrial systems. It integrates smoothly into any GIS, DMS or EMS supporting open system standards and enables the user to carry out balanced and unbalanced power flow. It has many features including fault analysis, harmonics, frequency scans, stability, EMT simulations, protection simulation and co-ordination, reliability, Maintenance Schedules, static and dynamic voltage stability, power dispatch, state estimation, optimal capacitor placement, cable sizing, built-in automation interface, interfaces for GIS and SCADA integration, and PSS/E compatibility. Trainees will have hands on experience with the software and will be solving exercises using PowerFactory.

    Course Instructor :
    Graduated with First Class Honours B.Eng. degree in Electrical and Electronic Engineering from University of Manchester, UK in 1994. He received his MBA degree from Edinburgh Business School, UK, in 1998. He then completed his M.Sc. in Electrical Power Engineering from University of Manchester Institute for Science and Technology (UMIST), UK in 1999. He completed his Ph.D. degree in Electrical Engineering from University of Manchester, UK in 2001. He worked for 12 years in oil and gas industry in major companies including Petroleum Development Oman and Shell UK as Senior Project Manager. He then joined Sultan Qaboos University in August 2002 as faculty member in the Department of Electrical and Computer Engineering. In addition to his academic duties, in the department, he was appointed as the Assistant Dean for Industrial Training and Alumni in the College of Engineering in 2006. In 2010 he was appointed as the Dean of Oman Maritime College. He has founded a number of successful companies to serve the needs of power system in Oman and the GCC region. He is currently the chairman of Albanah Group of Companies delivering a wide range of products and services including power system simulation softwares, hardwares, consultancies and technical and managerial training. His areas of interest include Power System Modelling and Simulation, Power System Protection, High Voltage Engineering, Privatization of Electrical Supply Industry, and Project Management. He has extensive experience in delivering training courses to senior managers and experienced engineers in public and privates sectors' organisations in the areas of Project Management, Power System Protection, and Power System Economics.
