An approach is proposed to solve multistage distribution network expansion planning problems considering future uncertainties, guiding the planner from production of expansion plans, evaluation of the plans under various future uncertain scenarios, to the selection of the best strategy. A new balanced genetic algorithm (BGA) is introduced that improves the intensification of the solution search procedure by trading-off diversification ability. This facilitates searching for the optimal solution, but also the efficient production of suboptimal solutions for the planner to take into consideration. The features of the BGA allow a multistage planning problem to be solved more efficiently; the BGA can consider a set of expansion plans in an early planning stage in a single run and produce planning strategies required to solve network problems in a later stage along the planning horizon. The overall performance of each plan under different uncertain scenarios is evaluated using a modified data envelopment analysis to assist decisions on which solution to adopt. The approach is applied to a multistage greenfield distribution network expansion problem considering scenarios for the location of future loads. The results clearly show the advantages of the approach over more conventional methods. © 2010 IEEE.

eCAP is an innovative power network planning and analysis tool for self-assessment of network capacity for DG connection. eCAP provides Distributed Generation (DG) developers with the ability to analyse the viability of conventional and ANM grid connections prior to making a connection application. DG Developers are able to choose a Point of Connection (PoC) in the network and receive an estimate of the available network capacity based on the type of generation technology and rated capacity. Currently, no such tool is available to support DG Developers who are forced to undertake complex studies using specific power systems analysis software and sophisticated techniques to determine the available capacity at a given PoC. eCAP tackles this problem using a modular software solution based on original power system modelling and analysis techniques. eCAP deals with this complex problem while delivering an intuitive and straightforward interface to the users. eCAP has an intuitive, web-based platform for DG developers to consider the feasibility of ANM-based connections and allows DSOs to vastly improve their customer service by identifying opportunities for ANM solutions to free a large portion of network capacity that otherwise would not be accessible. It has been successfully demonstrated as a proof of concept as part of the Accelerating Renewable Connections project (2012-2015) in a limited grid area with many connection requests defined by the DSO, SP Energy Networks. eCAP will enhance and support the existing SGS real time control products portfolio with a new product in planning tools. This feasibility study focuses on enhanced market analysis, the benefits and feasibility of re-platforming eCAP for being commercially fit, and identifying the requirements and design of new analytical and user interface functionality.

OPTIMISED aims to develop novel methods and tools for deployment of highly optimised and reactive planning systems that incorporate extensive factory modelling and simulation based on empirical data captured using smart embedded sensors and pro-active human-machine interfaces. The impact of energy management on factory planning and optimisation will be specifically assessed and demonstrated to reduce energy waste and address peak demand so that operations that require or use less energy, can allow this excess energy to be re-routed to local communities. The OPTIMISED environment will use semantically enriched process modelling, big-data generation, capture and perform analytics to effectively support planning specialists, manufacturing engineers, team leaders and shopfloor operatives throughout the systems lifecycle. These next generation manufacturing systems supported by data rich manufacturing execution systems with OPTIMISED technology will support a dramatic improvement in system performance, improved operational efficiency and equipment utilisation, real-time equipment and station performance monitoring, adaptation and resource optimisation. The OPTIMISED vision will be achieved by developing systems which are able to: 1. Monitor system performance through an integrated sensor network, automatically detecting bottlenecks, faults and performance drop-off 2. Continuously evolve to respond to disruptive events, supply chain disruptions and non-quality issues through factory simulation modelling 3. Improve understanding and monitoring of energy demand curve and energy usage per industrial process and globally improve efficiency of production line through reduced energy waste 4. Understand potential benefits, added value and impacts of participating in Demand Side Response (DSR) processes and becoming an active player in the changing energy industry, instead of remaining a conventional passive element that simply acquires a service from energy providers.
Over the past year, the Department of Energy has been putting an increased focus on technology to integrate renewable energy into everyday grid operations. This work has included opening loan guarantees to distributed renewables, grants to support field tests of distributed energy integration, and future funding plans to support the development of grid modernization technologies. Now the DOE’s blue-sky research agency, ARPA-E, is getting into the action -- or, as befits its mission, ahead of the action. Last month, ARPA-E announced $33 million in grants for its Network Optimized Distributed Energy Systems (NODES) program, meant to help 12 university, corporate and DOE laboratory projects that are trying to turn grid-edge assets into networked “virtual storage” systems. These projects are meant to “enable real-time coordination between distributed generation, such as rooftop and community solar assets, and bulk power generation, while proactively shaping electric load.” That could allow utilities to manage greater than 50 percent renewable penetration on the grid, “by developing transformational grid control methods that optimize use of flexible load and distributed energy resources.” This is not a unique concept. Distributed energy resource management software, or DERMS, platforms are being developed to tackle this challenge in one way or another, with grid giants like Siemens and Toshiba and startups such as Spirae, Enbala, Integral Analytics and Smarter Grid Solutions providing different pieces of the puzzle. Beyond that, there’s work being done by consortia such as Duke Energy’s Coalition of the Willing and Pacific Northwest National Laboratory's transactive energy pilot project to allow lots of distributed energy assets to communicate and act in concert to solve local and system-wide grid challenges. Some of the projects funded by ARPA-E’s NODES program would help support these kinds of ongoing distributed energy resource (DER) integration efforts, while others would go several steps beyond what today’s utility grid control platforms and DERs are built to handle. Here’s a short description of each project and its aims.
