Virtual Power Plant (VPP) have been proposed as an effective way to aggregate large portfolios of Distributed Energy Resources (DERs) and coordinate them to behave as a single functional unit in both the network and the market. This research narrative proposes that business models that can combine Internet platforms such as Peer-to-peer networks, with VPP to collectively manage DERs, are ideal systems for socially innovative business models to accomplish scale and replication and drive systemic change in the power system. This project lays conceptual foundations to design and simulate such a system. An urban social electricity-trading network is presented using the City of Melbourne as case study. Modelling is performed by applying an optimisation framework to a portfolio of household datasets with solar, simulated storage and flexible demand capabilities; a local community windfarm and large business buildings. Initial simulations show that internal energy trading between members of such a social energy network is highly dependent on local market conditions. However, having the ability to simultaneously operate as a small-scale generator, retailer and demand response coordinator might be the factors allowing these alternative business models to be feasible under various conditions.

Being one of the key derivatives of phasor measurement units (PMUs), a synchrophasor-only linear state estimator (LSE) presents a reliable, high quality, and truly dynamic picture of the power grid. However, with the increase in number of buses monitored by PMUs, computational burden will become a critical constraint for the state estimation solver. Although installing additional hardware can be a possible solution, such a solution will considerably raise the cost of capital investment, operation, and maintenance. This paper proposes cloud-computing as a cost-effective alternative to the computational burden problem. This paper also presents feasibility of the cloud based solution with regards to scalability of the system and latency incurred. Our solution is designed to address the critical operational parameters such as latency and variable network sizes. Additionally, the LSE application establishes robust communication procedures to process inputs arriving at high data rates from multiple PMUs. The paper concludes by highlighting future research directions for enhancing such cloud based solutions.

In order to meet the development goals of distribution networks while maintaining the environment to continue to provide the natural resources and ecosystem services upon which the economy and society depends, distributed energy resources have been continuously integrated on the grid. Assessing the impacts of integrating those distributed energy resources and evaluating the sustainability of the distribution networks has become important issues. This paper explores the assessment of the sustainability of active distribution networks with various types of distributed energy resources. Firstly, the stochastic models of the distributed resources are considered. Then, the distribution network development models are established utilizing system dynamics method. And the system sustainability evaluation is carried out by utilizing a modified analytic hierarchy process method integrated with entropy weighting and fuzzy theory. Finally, the feasibility and effectiveness of the proposed evaluation system has been demonstrated on a modified IEEE 33-bus system.

This paper proposes a method of enabling photovoltaic (PV) power plants to participate in primary frequency response by providing synthetic inertia (SI). This variation, referred to as communication enabled synthetic inertia (CE-SI), utilizes communication capabilities to provide global system frequency information to PV plants to emulate the inertial response of synchronous generators. The performance of CE-SI is analyzed with respect to the challenges associated with communication, such as latency and availability. Results indicate improvements in frequency response over SI using local frequency measurements when communication latency is sufficiently small.

This paper aims at developing an economic dispatch optimizer using a Particle Swarm Optimization (PSO) for a microgrid system, that can operate in grid-connected or islanded mode. In grid-connected mode, the optimizer provides set-points for dispatch of real power from Distributed Energy Resources (DERs) in the microgrid and purchase of real power from the bulk grid every 15 minutes. The optimization objective is to minimize operating costs of the microgrid while maintaining real power balance. In islanded mode, the optimizer provides setpoints for DERs, battery storage system and load curtailment to maintain reliable real power supply. The optimizer set-points are validated on a three-phase unbalanced microgrid model developed using the distribution system simulator GridLAB-D.

This paper evaluates the potential energy and power savings from application of Conservation Voltage Reduction to buildings with load diversity. Slow and fast voltage change experiments were performed to develop regression models with which the conservation voltage reduction energy and power factors were evaluated on a subject building. Least mean squares algorithm was used for the estimation of these parameters. The experimental results of 6 months of recordings captures not only the enforced voltage changes but also the existing voltage deviations on a feeder, weather conditions and load patterns.

A hierarchical control algorithm was developed to utilize photovoltaic system advanced inverter volt-VAr functions to provide distribution system voltage regulation and to mitigate 10-minute average voltages outside of ANSI Range A (0.95–1.05 pu). As with any hierarchical control strategy, the success of the control requires a sufficiently fast and reliable communication infrastructure. The communication requirements for voltage regulation were tested by varying the interval at which the controller monitors and dispatches commands and evaluating the effectiveness to mitigate distribution system over-voltages. The control strategy was demonstrated to perform well for communication intervals equal to the 10-minute ANSI metric definition or faster. The communication reliability impacted the controller performance at levels of 99% and below, depending on the communication interval, where an 8-minute communication interval could be unsuccessful with an 80% reliability. The communication delay, up to 20 seconds, was too small to have an impact on the effectiveness of the communication-based hierarchical voltage control.

LVDC (Low Voltage Direct Current) distribution systems have advantages over conventional AC distribution systems in terms of power quality, power-conversion-loss reduction, renewable energy integration, and so on. There were pioneering researches into development of LVDC distribution systems but most of them considered radial distribution systems with one grid-connection converter. In this paper, we propose multi-terminal LVDC distribution system that has multiple grid-connection points and integration of distributed energy resources (DERs). The multi-terminal LVDC system can have more reliability and flexibility in electric power provision because it has multiple grid-interfacing AC/DC converters. However, multiple paths for power flows can increase the complexity in system operation and control. This paper proposes a new voltage control method for multi-terminal LVDC distribution systems using multi-agent system (MAS). This paper presents the hierarchical control algorithms to coordinate multiple AC/DC converters and DERs. Simulation studies demonstrates the performance of the proposed method.

Migrating to a smart grid requires a paradigm shift in the implementation of power system applications. With the advent of IEC 61850, contemporary Substation Automation Systems (SAS) are utilizing electronic instrument transformers and merging units to transmit current and voltage measurements over Ethernet as Sampled Measured Values (SMV). However, if a substation's network resources are not properly managed, the high transmission rate of SMV would make them prone to packet loss. Also, the strict 4ms time constraint imposed on SMVs makes encrypting these messages nearly impossible. As such, this paper presents an online device level fake data detection system for detecting fake SMV messages without violating the 4ms time constraint set forth by IEC 61850. In order to ensure a reliable SAS operation, this paper also presents a coupled neural network — time series method for forecasting lost SMV packets. The proposed algorithm was implemented in a system composed of merging units and intelligent electronic devices developed for this purpose. Real-time experimental results of the proposed algorithms over a real IEC 61850 network showed excellent results in terms of detecting fake messages and increasing the robustness of protection schemes by accurately forecasting dropped SMV packets.
