Published on

Slovenian- Japanese project NEDO, is a three-year project, where management of electricity consumption in households is being implemented. It enables electricity consumers to actively manage their energy consumption and save money on electricity bills. The initiative is also expected to be beneficial for Slovenian electric power operators through preparing advanced infrastructure framework to improve their service quality.
In this project, Solvera Lynx provides software development, development of the electrical energy consumption management system (Demand Response Control System), hardware development and coordination’s of the installation of LoRaWAN wireless communication devices - Direct Load Control (ComBox.L DLC) devices for direct disconnection and the equipment for the energy consumption management in households (HEMS).

Introduction of a smart grid on a national level within NEDO project.

  1. 1. PROVIDE GREATER RELIABILITY TO THE GRID WITH ENGAGEMENT OF ACTIVE COMMERCIAL AND RESIDENTIAL USERS solvera-lynx.com Demand Response Control System for Distribution and Transmission System Operator Use case: NEDO project – Slovenian-Japanese Direct Load Control device Main functionalities of ComBox.L DLC device are LoRaWAN class c which supports bi-directional communication between the end device and the Demand Response Control System (DRCS), transferred in real time. ComBox.L DLC is an innovative wireless direct load control device for today’s smart grid control. It is based on LoRaWAN, a Low Power Wide Area Network technology, which supports remote control of connected appliances. ComBox.L DLC devices use spread spectrum modulation allowing coverage of up to 5km in dense urban areas and up to 10km for countryside applications. GemaLogic Flexibility – Demand Response Control System for Commercial and Residential Users Theunpredictabilityoftheconsumptionofprosumers,electricvehiclesandelectricitygeneration,especiallyfrom renewable sources, has an increasing impact on the stability of the functioning of the electric power system. The high unpredictability of the consumption and production of electricity is influenced by the accelerated time of digitisationandelectrificationasaresultofthesustainabilityandactivereductionofcarbonfootprintinallareas. TheGemaLogicFlexibilityplatformenableseasyconnectivitywithalltypesofenergyloadsanddistributedenergy resources, thus contributing to a more reliable operation of the electric power system, sustainability, lowering the carbon footprint, as well as providing optimal balancing of balance groups on the wholesale energy market. The GemaLogic Energy Flexibility platform provides innovative control of flexible loads and distributed energy resources which can adapt their electricity production or consumption. The GemaLogic Flexibility platform provides Demand Side Management functionalities as a modular solution for Energy Efficiency and Demand Response functionalities. It provides the following tools to participate in the ancillary services market, balancing markets or wholesale energy markets: • Ancillary services (providing a secondary or tertiary reserve); • Flexible energy loads in industry (glass and steel industry); • Flexible energy loads in households and buildings for providing flexible loads (Direct Load Control Management, Critical Peak Pricing with and without control);
  2. 2. RESULTS AND BENEFITS • 97% of active users want to participate in further similar projects • 43% of active users have decided to participate due to financial incentives SOLUTION 1. DRCS • Aggregation of the commercial and residential active users • IEC 61968 (CIM / Distribution manage- ment) • Direct Load Control Management Con- sumption and demand response forecast • Aggregation of forecasts • Activation support • Alarms and Events (SMS, e-mail) • Activation reports • 2. DIRECT LOAD CONTROL Availability • User participation • Control 3. HEMS and ComBox.L DLC • Provide access to control loads at 1 and 15 min intervals The DRCS offered direct load control through aggregating the commercial and residential active users providing demand response functionality. Instead of investing in grid expansion, DSO Elektro Maribor and TSO ELES have benefited from the use of advanced secondary equipment, information and communication technologies, and cloud solutions to enable better exploitation of the existing power grid. DRCS is a GemaLogic Flexibility platform for providing demand response functionalities for commercial and residential active users. DRCS was developed for providing direct load control in times of critical peak tariffs and for ancillary services (tertiary reserve). DRCS is designed to provide Direct Load Control management (based on SMS and e-mail informing, connectivity to House Energy Management Systems and ComBox.L DLC devices), collect billing data every 15 minutes (from Meter Data Management installed at the Distribution System Operator through a Common Information Model (CIM)) and execute demand response activation. Billing data are processed and prepared analytically to provide energy consumption forecasts and at the same time provide demand response potential for the next 24 hours. Energy consumption and demand response potential are automatically exchanged with the Distribution Management System (iDMS). When iDMS recognises high power demand in the distribution network, it automatically prepares a request for activation in DRCS. Scheduled activation informs all active users and sends a message to all controlled devices schedules to disconnect appliances in times of activation. Results and BenefitsSolvera Lynx’s GemaLogic Flexibility – DRCS for Commercial and Residential usersIntroduction The Demand Response Control System (DRCS) was developed within the Slovenian-Japanese project called NEDO.The NEDO Project – Slovenian-Japanese partnership – is a partnership between the Japanese agency NEDO and the Slovenian transmission system operator ELES.Within the framework of this project, advanced functionalities have been established in order to provide for better coordination between stakeholders in the electricity system and more efficient operation of the system. NEDO is a three-year smart grid project whose principal partners are NEDO and its authorised contractor Hitachi, and the ELES company. Alongside ELES, a large number of stakeholders from Slovenia are participating in the project, which is why it can rightfully be called a national project and the only one of its kind in Europe. CHALLENGES • Integration of existing systems • Better exploitation of the existing grid. From the aspect of the electricity system, the challenges of the project are in the use of advanced solutions that can respond to the challenges of modern electricity systems in the light of sustainable development by means of environment-friendly solutions. Instead of investing in grid expansion, the use of advanced secondary equipment, information and communication technologies, and cloud solutions will enable better exploitation of the existing grid..
