Integration of OpenADR with Node-RED for Demand Response Load Control Using Internet of Things Approach

2017-03-28
2017-01-1702
The increased market share of electric vehicles and renewable energy resources have raised concerns about their impact on the current electrical distribution grid. To achieve sustainable and stable power distribution, a lot of effort has been made to implement smart grids. This paper addresses Demand Response (DR) load control in a smart grid using Internet of Things (IoT) technology. A smart grid is a networked electrical grid which includes a variety of components and sub-systems, including renewable energy resources, controllable loads, smart meters, and automation devices. An IoT approach is a good fit for the control and energy management of smart grids. Although there are various commercial systems available for smart grid control, the systems based on open sources are limited. In this study, we adopt an open source development platform named Node-RED to integrate DR capabilities in a smart grid for DR load control. The DR system employs the OpenADR standard.

The New Wireless Frontier: Home and Vehicle Connectivity

Our customers expect in their vehicles the same constant connectivity that they experience in their homes through high speed internet portals. New services based on these advances will be transparent and ubiquitous - completely integrated into our lives, just as electricity comes to the wall socket or water from the faucet. The Wi-Fi Radio implements this vision using Wireless Fidelity (Wi-Fi) based on the suite of IEEE 802.11 standards. Drivers have constant wireless connectivity and personalized digital content made available to them through the Wi-Fi Radio. Ford and our partner Delphi developed the Wi-Fi Radio to overcome the inherent functional and packaging limitations of our vehicles, to quickly introduce new technology at affordable prices and to seamlessly integrate new services into the vehicle. We chose the radio as the integration site because the radio is accessible to every customer and affordable on every vehicle.

Route-Optimized Energy Management of Connected and Automated Multi-Mode Plug-In Hybrid Electric Vehicle Using Dynamic Programming

This paper presents a methodology to optimize the blending of charge-depleting (CD) and charge-sustaining (CS) modes in a multi-mode plug-in hybrid electric vehicle (PHEV) that reduces overall energy consumption when the selected route cannot be completely driven in all-electric mode. The PHEV used in this investigation is the second-generation Chevrolet Volt and as many as four instrumented vehicles were utilized simultaneously on road to acquire validation data. The optimization method used is dynamic programming (DP) paired with a reduced-order powertrain model to enable onboard embedded controller compatibility and computational efficiency in optimally blending CD, CS modes over the entire drive route.

A Cloud-Based Simulation and Testing Framework for Large-Scale EV Charging Energy Management and Charging Control

The emerging need of building an efficient Electric Vehicle (EV) charging infrastructure requires the investigation of all aspects of Vehicle-Grid Integration (VGI), including the impact of EV charging on the grid, optimal EV charging control at scale, and communication interoperability. This paper presents a cloud-based simulation and testing platform for the development and Hardware-in-the-Loop (HIL) testing of VGI technologies. Although the HIL testing of a single charging station has been widely performed, the HIL testing of spatially distributed EV charging stations and communication interoperability is limited. To fill this gap, the presented platform is developed that consists of multiple subsystems: a real-time power system simulator (OPAL-RT), ISO 15118 EV Charge Scheduler System (EVCSS), and a Smart Energy Plaza (SEP) with various types of charging stations, solar panels, and energy storage systems.

Development and Validation of Dynamic Programming based Eco Approach and Departure Algorithm

Eco Approach and Departure (Eco-AnD) is a Connected Automated Vehicle (CAV) technology aiming to reduce energy consumption for crossing a signalized intersection or set of intersections in a corridor that features vehicle-to-infrastructure (V2I) communication capability. This research focuses on developing a Dynamic Programming (DP) based algorithm for a PHEV operating in Charge Depleting mode. The algorithm used the Reduced Order Energy Model (ROM) to capture the vehicle powertrain characteristics and road grade to capture the road dynamics. The simulation results are presented for a real-world intersection and 20-25% energy benefits are shown by comparing against a simulated human driver speed profile. The vehicle-level validation of the developed algorithm is carried out by performing closed-course track testing of the optimized speed solutions on a real CAV vehicle.

Energy Savings Impact of Eco-Driving Control Based on Powertrain Characteristics in Connected and Automated Vehicles: On-Track Demonstrations

This research investigates the energy savings achieved through eco-driving controls in connected and automated vehicles (CAVs), with a specific focus on the influence of powertrain characteristics. Eco-driving strategies have emerged as a promising approach to enhance efficiency and reduce environmental impact in CAVs. However, uncertainty remains about how the optimal strategy developed for a specific CAV applies to CAVs with different powertrain technologies, particularly concerning energy aspects. To address this gap, on-track demonstrations were conducted using a Chrysler Pacifica CAV equipped with an internal combustion engine (ICE), advanced sensors, and vehicle-to-infrastructure (V2I) communication systems, compared with another CAV, a previously studied Chevrolet Bolt electric vehicle (EV) equipped with an electric motor and battery.

As wireless devices and cellular networks continue to evolve, opportuvnities are created for enhancing the overall user experience with telematics related services. This paper discusses the pros and cons of por phone systems and embedded phone systems as conduits for telematics applications. Methods to enhance embedded in-vehicle telematics systems to include operation with handheld wireless devices on both Wide Area Networks (WAN) and Wireless Local Area Networks (WLAN) will also be presented. Services will be discussed that allow vehicles and wireless devices to interact with each other and with remote servers. Implementation options will be explored along with an analysis of the key players in the telematics supply chain (i.e., OEMs, Suppliers, Carriers, Call Centers, Consumers) who ultimately benefit from each approach.
