This paper presents a grid-tied microgrid testbed for development and verification of automated energy storage management systems. Different assets in the microgrid including renewable generation, programmable load and a battery unit are introduced. Structure of the communication network to monitor and control the assets is also described in details. Based on the microgrid configuration, a cent...

During the microgrid search process, optimal allocation and economic dispatch are very important and are interrelated, having interaction and mutual checks. In this paper, we adopt a bilevel planning method to search for the multi-objective optimal allocation of a microgrid, considering economic dispatch. The upper level is the optimal allocation, which aims at minimizing the daily fixed cost o...

Recent research has demonstrated the vulnerabilities of cyber physical microgrid to different rates of denial-of-service (DoS) attacks, which send internal requests to degrade the victim’s performance. However, the interaction between the attacks and the security of microgrid remains largely unknown. In this paper, we address two fundamental questions: (1) What is the impact of intermittent DoS...

Imagery from microgrid polarimeters is obtained by using a mosaic of pixel-wise micropolarizers on a focal plane array (FPA). Each distinct polarization image is obtained by subsampling the full FPA image. Thus, the effective pixel pitch for each polarization channel is increased and the sampling frequency is decreased. As a result, aliasing artifacts from such undersampling can corrupt the tru...

This paper presents a model for calculating the optimal size of an energy storage system (ESS) in a microgrid considering reliability criterion. A larger ESS requires higher investment costs while reduces the microgrid operating cost. The optimal ESS sizing problem is proposed which minimizes the investment cost of the ESS, as well as expected microgrid operating cost. Utilizing the ESS, genera...

An optimal scheduling model for a microgrid participating in the electricity distribution market in interaction with a Distribution Market Operator (DMO) is proposed in this paper. The DMO administers the established electricity market in the distribution level, sets electricity prices, determines the amount of the power exchange among market participants, and interacts with the Independent Sys...

This paper discusses how an Active Power Filter (APF) can be utilized for system-wide harmonic mitigation in a microgrid with multiple sources of harmonic distortion located at different buses. A two-bus microgrid system with independent nonlinear loads at both buses is first investigated analytically, and it is demonstrated that it is possible to derive a harmonic current injection from the AP...

This paper gives a correctness proof for the on-chip COMA cache coherence protocol that supports the Microgrid of microthreaded architecture, a multi-core architecture capable of integrating hundreds to hundreds of thousands of processors on single silicon chip. We use the Abstract State Machine (ASM) as a theoretical framework for the specification of the on-chip COMA cache coherence protocol....

The work is focused on modeling Smart Grid functional requirements using use case descriptors and UML class diagrams. The design patterns help identify appropriate agents in the event of any outage in a microgrid. The paper presents selective UML diagrams for different layers in a multi agent design for a power system called UML-MAPS. The architecture is cost effective, easy to track, manage an...

This paper presents an overview of our body of work on the application of smart control techniques for the control and management of microgrids (MGs). The main focus here is on the application of distributed multi-agent system (MAS) theory in multi-objective (MO) power management of MGs to find the Pareto-front of the MO power management problem. In addition, the paper presents the application ...
