This paper presents a new, adaptive strategy for substation feeder protection implemented with state-of-the-art digital signal processing technology. This feeder protection adapts its trip settings to provide improved selectivity and speed of fault detections for varying power system configurations and loadings. This protection accurately senses and de-energizes downed conductors that often could not be detected by conventional non-adaptive feeder protections. Several people are killed every year by contacting with live downed conductors. This adaptive protection is designed to significantly reduce this potentially fatal condition. This paper presents the design of this adaptive feeder protection. Several power system faults were simulated under varying load and system conditions. The results are analyzed to verify the design, to determine the improvement over a conventional static protection, and to verify the correct protection operation. Field tests were conducted in Runnymede Transformer Station in Ontario to validate this adaptive feeder protection

Power system modernization with increasing operation automation and integration results in growing computer network access. This facilitates cyber-attackers' capabilities to assume control over power system operations that could cause serious blackouts. Security therefore becomes a critical issue for DNP3, a commonly used protocol for power system communications. This paper proposes cyber-security based on Pretty Good Privacy (PGP) for DNP3 to strengthen computer network security. This PGP-based cyber-security provides authentication capabilities using public key cryptography, with enhanced performance using symmetric keys for most of the encryption. This paper provides a symmetric cipher key exchange mechanism using PGP-based cyber-security to further enhance the power system security. The proposed PGP-based cyber-security is implemented as a pseudo-layer below the DNP3 data-link layer to minimize any impact on the DNP3 specifications and the operations of original DNP3 devices. This PGP-based cyber-security provides confidentiality, identity authentication, transmission content authentication, and nonrepudiation
电力系统现代化,随着运行自动化和集成化程度的提高,计算机网络接入日益增多。这使得网络攻击者有能力控制可能导致严重停电的电力系统运行。因此,作为电力系统通信的常用协议,安全性成为DNP3的关键问题。为了加强计算机网络的安全性,本文提出了基于PGP (Pretty Good Privacy)的DNP3网络安全方案。这种基于pki的网络安全提供了使用公钥加密的身份验证功能,并在大多数加密中使用对称密钥增强了性能。为了进一步提高电力系统的安全性,本文提出了一种基于pki的对称密码密钥交换机制。提议的基于pp的网络安全是作为DNP3数据链路层下面的伪层实现的,以尽量减少对DNP3规范和原始DNP3设备操作的影响。这种基于pki的网络安全提供了保密性、身份认证、传输内容认证和不可否认性

With the increasing penetration of distribution generation (DG), micro-grid operation becomes an attractive and valuable option. In order for micro-grids to become a viable option, issues such as micro-grid control and protection must be addressed and well established. The paper focuses on micro-grid protection and proposes the use of directional overcurrent relays for protecting a micro-grid consisting of synchronous based DGs. The key issue in selecting the relay settings is to achieve the minimum possible operating times while maintaining coordination among all relays. In this paper, the relay coordination problem is formulated as a mixed integer nonlinear programming (MINLP) problem and is solved using particle swarm optimization (PSO)

Open access to the power grid through privatization and environmental concerns are changing the way power systems are built and operated. Many in the power industry are looking to integrate smaller "green" generators into their distribution systems (DSs), which traditionally contain no sources of power generation. Such "green" technologies include wind, solar and small hydro generation. Traditional analysis tools need to be modified to facilitate distribution systems with embedded generation. This paper reports on a distribution load flow (DLF) for DSs with embedded generation. This DLF makes use of a recursive function and a specialized data structure designed to take advantage of the radial nature of DSs. The resulting DLF is fast, flexible and computationally efficient

The stability of large-scale power systems has been well studied in the past three decades. However, the stability of power distribution systems in the presence of privately own generation virtually has not been studied. Power distribution system stability concerns increase rapidly as the demand for open access to the electric power systems for generation and trading under new government deregulation policies grows. This paper describes an adaptive control of generator excitation system, based on step-ahead predictive control method for improvement of the dynamic stability of power distribution systems, particularly the weakly inter-connected ones. This predictive control is based on the minimization of a performance index which is defined as a weighted combination of four key factors: deviation of generator terminal voltage from its reference voltage; difference of mechanical and electrical torques; increment of rotor speed; and increment of rotor flux linkage

This paper presents a particle swarm optimization (PSO) algorithm to solve an economic-emission dispatch problem (EED). This problem has been getting more attention recently due to the deregulation of the power industry and strict environmental regulations. It is formulated as a highly nonlinear constrained multiobjective optimization problem with conflicting objective functions. PSO algorithm is used to solve the formulated problem on two standard test systems, namely the 30-bus and 14-bus systems. Results obtained show that PSO algorithm outperformed most previously proposed algorithms used to solve the same EED problem. These algorithms included evolutionary algorithm, stochastic search technique, linear programming, and adaptive Hopfield neural network. PSO was able to find the Pareto optimal solution set for the multiobjective problem. In addition, PSO results were compared to LINGO software outcomes. Comparison results signify the effectiveness and robustness of PSO as a promising optimization tool for this specific problem

The paper presents the application of Neural Network technique as a pattern recognition to high impedance faults (HIFs). The relay is based on a novel low-frequency (3rd and 5th harmonic feature diagnostic vector). The currents and voltages are used as a featured extracted signals for fault discrimination. The focus of this paper is to design a robust ANN-based relay, which can determine the high impedance low current faults on distribution radial electrical systems. A variety of faults and system conditions have been simulated to evaluate the reliability and sensitivity of the proposed technique.

Critical and sensitive loads are growing rapidly as consequences of increasing demands of precision control and energy efficiency. These loads require a quality power supply and are particularly vulnerable to supply disturbances. This paper presents a simple, cost-effective multiple-function power electronic converter that significantly enhances the power quality at the service entrance to critical and sensitive loads. This converter is capable of processing multiple power conversions in a single-stage power electronic circuit. This paper describes four key operations of this converter: Active power line harmonics filtering, Uninterruptible power supply, Industrial energy storage conversion, and Reactive power compensation. In standard practices, each of these operations may require at least one power converter. The multiple-functions converter presented in this paper can carry out all these operations individually using one single-stage power electronic circuit. This paper details the design of this converter and provides simulations of the converter performance validated with experimental results.

There has been increasing peer-to-peer networking among intelligent electronic devices (IEDs) with communication capabilities for efficient power system protection, control and monitoring with connections to external networks. This facilitates cyber-attackers' capability to assume control over power system operations that could cause serious blackouts. This paper proposes a new data-object-rule-based (DORB) cyber-security implemented as a pseudo-layer below the DNP3 application layer, a commonly used protocol for power systems communications, to strengthen the power system computer network security. The DORB cyber-security limits effectiveness of cyber-attacks by implementing rule-based cyber-security for the usage of DNP3 function codes, object types, and data sets. Any data transmission that does not conform to the allowed data object usage is blocked from being transmitted or received by the DNP3 devices. The DORB security also incorporates authentication between peers for particular function codes, object types, and data sets, to improve the power system communication security.

There has been increasing use of intelligent electronic devices (IEDs) with communication capability for modern power distribution system protection, control and monitoring. This increases the need of LANs for IEDs to exchange data for improved and coordinated operations through peer-to-peer networking. Distributed Network Protocol (DNP3), commonly used for power system communications, is lack of effective internetworking LANs and individual IEDs. To improve the internetworking capability, this paper proposes a network address mechanism (NAM) that provides dynamic routing operations and a variable address field. The NAM is designed to provide WAN internetworking capabilities that can be implemented for IEDs with minimal effects on the network specifications, such as continuous use of established network addresses. The NAM is also designed to provide the capability for unlimited WAN expansion regardless of network structures and to enhance the network cyber-security.
