This paper presents a new modeling framework for analysis of impact and scheduling of price-responsive as well as controllable loads in a three-phase unbalanced distribution system. The price-responsive loads are assumed to be linearly or exponentially dependent on price, i.e., demand reduces as price increases and vice versa. The effect of such uncontrolled price-responsive loads on the distribution...
Demand response is a key solution in smart grid to address the ever-increasing peak energy consumption. With multiple utility companies, users will decide from which utility company to buy electricity and how much to buy. Consequently, how to devise distributed real-time demand response in the multiseller̈Cmultibuyer environment emerges as a critical problem in future smart grid. In this paper, we...
This paper investigates the optimal charging strategy for a plug-in electric taxi (PET) to maximize its operating profit by choosing proper charging slots, subject to uncertain electricity prices and time-varying incomes. As PET consumes more electricity and possesses different charging behaviors from the widely studied private electric vehicles, this problem deserves special treatment. First, in...
In restructured power systems, the transmission and distribution grids are autonomously utilized by independent system operator (ISO) and distribution companies (DISCOs), respectively. As the operating condition of one grid influences the decisions made by operators of other grids, the ISO and DISCOs should collaborate and cooperate with each other in order to operate the entire power system in a...
An independent generation company (GenCo) secures its future trading position by managing its portfolio among multiple trading options. Future returns of these trading options are not known during decision making and are traditionally estimated using probabilistic or fuzzy methods. Quantifying such uncertainty of market returns by conventional methods does not reflect the information gap existing...
Uncertainty in consumption is a key challenge at energy utility companies, which are faced with balancing highly stochastic demand with increasingly volatile supply characterized by significant penetration rates of intermittent renewable sources.
This paper describes the development of a modern power system laboratory within a Bologna Declaration compliant curriculum at the Department of Energy and Power Systems, Faculty of Electrical Engineering and Computing, University of Zagreb. The paper describes laboratory components and provides insight into the experiments that students are required to perform. The laboratory course is divided into...
This paper presents a novel modeling framework for the analysis of Plug-in Electric Vehicle (PEV) charging in unbalanced, residential, distribution systems. A Smart Distribution Power Flow (SDPF) framework is proposed to determine the controlled or smart charging schedules and hence address the shortcomings of uncontrolled charging. The effect of peak-demand constraint imposed by the Local Distribution...
Fossil fuel generation companies (GenCos) trade in multiple uncertain energy markets: fuel and carbon markets on upstream side while electricity market on downstream side. Global economic and environmental benefits lead these markets to pursue overlapping goals, making them highly interactive. GenCos may identify optimal trading strategies for upstream and downstream trading in an integrated framework,...
The objective of this paper is to present some discussions about data treatment in the new environment existing in the power systems and smart-grids. The paper presents some aspects of the data acquisition, communication, and security, and data amount, management, and mining. In this paper, some ideas are proposed to inspire discussions about the above themes. The goal of these discussions is to provide...
In recent years, the increasing demand of electricity and the new technology applied in the electrical engineering (EE) bring many challenges to the research and education of China's industry and university. In order to adapt to such changes, the industry, university and government put much efforts on the industry-academic and education cooperation. This paper describes the background, status and...
The planning of distribution network is faced with a great challenge when large-scale renewable energy mostly wind power entering into power system. This paper proposes a bi-level programming model considering distributed wind generation (DWG) allocation in the active distribution network environment which introduces active management fee (AMF) concept firstly. The bi-level programming is a complex...
In this paper, game design for demand response in smart grid from a control perspective is investigated. A pricing scheme is proposed to ensure the efficiency of the Nash equilibrium. The designed game is proven to be a state-based potential game and the stationary state Nash equilibrium is the social optimal solution. An adaptive penalty based pricing mechanism is proposed and adaptive control laws...
Demand side management has attracted a lot of attention as a method to regulate customer behavior and improve system reliability. In this paper, we solve the day-ahead energy pricing problem in the distribution electricity system by taking into account the fact that customers can change their consumption behavior in response to price changes. We propose two pricing models under two different scenarios...
Industry needs further development of methodologies and models for analyzing cascading outages. • Cascading outages need to be analyzed in both steady state and transient domain. • Practical approaches need to fully simulate protective relays operation • Models need to incorporate RAS and operating procedures into the analysis • Improve visualisation and decision support tools to reduce human error...
