Tutorial -1: Frequency control of low-inertia islanded power systems

 

The gradual proliferation of distributed energy resources (DERs) such as photovoltaic (PV) systems is of interest to utilities of remote and rural areas where the use of conventional power generation is costly. Over the past decade, Horizon Power (the local utility supplying remote and regional towns of Western Australia) has experienced substantial growth in the installation of PV systems by its customers, particularly in the remote town of Carnarvon. The increasing number of distributed energy resources connected to the grid has created several challenges to the utility. Considerations of the sustainability and cost-effectiveness of PV generation, along with the customers' interest in renewable energies, have been the drivers for a project, aimed at identifying the ways to increase the penetration of PV systems, as well as to resolve the associated technical and operational issues. The project involves several practical trials and experiments on the Carnarvon remote network to assess the system's capability to increase penetration of DERs. The overarching intention is to provide a quantitative approach to assessing the hosting capacity of DERs for remote networks across the state. The project focusses on:

  • investigating the technical impact of the DERs on the network and identify the solutions to overcome the barriers;

  • propose an effective way to increase the DER hosting capacity of the network, which can be replicated in other remote networks across the state.

Findings and experiences from the project will be shared during this tutorial.

Tutorial -2: Frequency control of low-inertia islanded power systems

The South West Interconnected System (SWIS) is the electricity grid that serves the southwestern part of Western Australia. Because the SWIS is an island system (disconnected from the NEM, the main grid that serves the eastern states of Australia), it must operate independently without any external support (e.g. interconnectors). With the massive uptake of rooftop PV, as well as the recent connection of large-scale wind and solar into the SWIS, there is a steady visible decline of synchronous inertia in the system. Reduced inertia and operational loads during the middle of the day (due to duck curve effects) make the control of system frequency more challenging as inertia provides an inherent and instantaneous response to active power imbalances (and thus retards changes in frequency). This tutorial surveys the state of the art when it comes to frequency control in low-inertia environments with specific operational case examples from the SWIS.

Tutorial -3: Frequency control of low-inertia islanded power systems

 

Along with the Smart Grid development, modern power systems are entering a “data-intensive” era. A vast volume of data from power grids is collected through advanced sensing and communication technologies, such as smart metering data, phasor measurement data, as well as meteorological data (e.g., wind speed and solar irradiance) related to renewable power generation, etc. 

Such data contains comprehensive information about the power system covering equipment’s health status, power grid’s static and dynamic characteristics, renewable power generation, customers’ electricity usage pattern, etc. Therefore, advanced data-analytics techniques are needed to convert such data to knowledge for practical applications.

This tutorial aims to present some typical applications of data-analytics techniques for smart grids. Specifically, we will focus on three topics covering both power grid and the end-user: 1) power system stability assessment and control, 2) smart meter data processing, and 3) knowledge discovery from smart meter data

The tutorial will cover the fundamental principles, enabling algorithms, and case studies as well as practical implementations of the above three topics. The tutorial will be open to students, researchers, engineers, and any interested attendees in this area. Through this tutorial, the attendees will acquire the basic knowledge in data-analytics for power system stability analysis, and knowledge discovery from smart meter data, and practical guideline for designing the data-analytics tools.

Tutorial -4: The emerging opportunities of servitization for market expansion in smart grids

The objective of the tutorial is to present a comprehensive introduction from the new paradigms in the servitization and market expansion practice of the smart power systems. It has been motivated by the great impact of IT-based revolution of technology in the innovative industries and the open up of new lines of service provision in the traditional industries. Therefore, definitely the smart power system is also affected and even driven by the factors of cause and effects of the IT revolution and of service provision, which will ultimately lead to change and alteration in the market model of the power systems. Hence, the tutorial will review the recent theories and paradigms in the marketing and market development of the IT-based industries in the smart grids. We would introduce different terms and ideologies on the logic of marketing and contrast the service-dominant logic of marketing to the good dominant logic of marketing. It also would justify the terms with the different phenomena in the traditional market structures and the modern market constructs and theories. The tutorial, besides, will present the relational marketing activities of the incumbent firms through which they keep the current consumers and promote the activities in face of the new entrants of the innovative companies, startups and spin-offs to the area of power market.

Tutorial -6: Voltage and frequency control in renewable-rich networks

Power system frequency and voltage control are of paramount importance to maintain power grid stability and security. With the large-scale integration of power electronic converter interfaced renewable power generation into power grids (e.g. wind generation and solar-PV), the conventional strategies to control and maintain system frequency and voltage are becoming inadequate. In some cases, inadequacy of frequency and voltage control resources in power grid has led to power system stability problems. Therefore, new strategies should be deployed in power grids to maintain frequency and voltage within acceptable levels stipulated in grid codes/ rules, such as by employing advanced control schemes in power electronic converter interfaced renewable generators (e.g. fast frequency response). This tutorial will cover both the depth and breadth of aspects of power system frequency and voltage control in renewable rich power grids including electricity market aspects related to frequency and voltage control. The outlines of the tutorial are:

Fundamentals of Power System Frequency and Voltage Control

- Frequency and Voltage Control Challenges with Renewable Power Generation

- Frequency and Voltage Control Strategies under High Renewable Power Penetration

- Frequency and Voltage Control from Electricity Market Perspective
