Challenges of the municipal utility provider Buchen

The distribution grid of the municipal utility provider Buchen will face new challenges, because of the continuous increase of renewable energies in the power generation. The municipal utility provider Buchen has to balance the high fluctuation in power generation and consumption. Otherwise the people might experience outages. The investments into the power grid are important for a sustainable and secure energy supply, but implies high investment costs.

Solution

By using innovative smart grid solutions like the new IT solution Venios Energy Solution (VES) investments can be dramatically reduced. While integrating actively contrallable net components, different fundamentals for planning and simulation, critical situations (e.g. congestions) can be identified beforehand and finally prevented by implementing the right measures. The use of VES brings transparency into the power grid. In each grid node, VES reliably calculates the current and voltage without using hardware components. Like this, a common distribution grid becomes a smar grid.

Project implementation

Venios analyzed the situation and determined in close collaboration with the municipal utility provider Buchen the implementation plan. In a first step, all data about the assets of the grid (e.g. power lines, trafos) including technical specifications (e.g. technical data of PV panels) are added to VES. In a second step, VES was configured according to the individual requirements and the three substations equipped with Janitza measurement hardware components were integrated into VES. In a last step, the VES system was introduced regarding the functions like net monitoring and simulation.

Outcome

Having a visualized distribution grid network, the possiblity to build scenarios about future grid states and simulate them, it is possible for the municipal utility provider Buchen to actively manage the grid by having an superior data basis. Having done this, the efficient network expansion and modification as well as the control of switchable operation units like the controllable substation, controllable section points or storage system are possible. Additionally, critical voltage situations will be securely identified beforehand.

Reference project B: Research project „Hybrid Grids DEMO“  in Hartberg, Austria

Challenge

The biggest challenge of the research project „Hybrid Grids DEMO“ lies in the multi-medium optimization of electricity/heat/cold. The current excessive electrical energy shall be provided by decentralized storage systems when consumers need it for a later application. In order a general concept is needed, which includes the control of the electrical and thermal network in order to optimize the test area.

Solution

The solution is to flexibilize the energy provision and energy usage system, which absorbs energy from the city area and the outer conurbation area and provides it later if needed. In this case, the system will sent out control signals to the demand side and the genereation side, how and when energy should be produced or used. The informationen about the state of the power grid is provided by the software solution Venios Energy Solution (VES) and Venios Energy Management (VEM). Venios Energy Solution gives transparency about flexiblities in the distribution grid and makes them usable for the business processes of the grid operator. The software solution Venios Energy Management (VEM) measures and calculates the optimal energy demand of households, businesses and industry clients on the basis of measured or modelled load curves.
In the end, there is no active but passive control, carried out by a very sensitive grid control system. In this way, the control system is in accordance with the regulatory framework and is able to be rolled out in a broader area. The decentralized actors will recive economic incentives from the optimizer and can decide by themselves (manually or automatically), if the follow the recommendation or not.

Implementation

Together with six project partners (Stadtwerke Hartberg • Forschung Burgenland GmbH • Technische Universität Wien • 4ward Energy Research GmbH • TBH Ingenieur GmbH• General Electric Austria GmbH) phase one of the project will be executed within one year to design the detailed planning and accomplish the preliminary studies for a demonstration. Then, in the coming two years, the installation of test objects, the pilot and monitoring of the system will follow. The pilot operations of a virtual pumped storage power system will be realized by bringing together the control of decentral consumers and producers as a virtual power plant and linking together the electricity, heat and cold network.

Result

The projects will achieve a reduction in CO2-emissions on the side of the demonstration objects in the direct manner and indirectly through ecological effects by the function operation of an energy storage. These savings can be expressed in the following way:

  • Harmonization of the grid profile (cost savings for the Stadtwerke Hartberg)
  • Increase in the direct usage rate of renewables in the project area and outer conurban areas (cost savings for endusers, the Stadtwerke Hartberg and a contribution to the energy efficiency law (in German: “Energieeffizienzgesetz))
  • Increase in the efficiency of the production (Stadtwerke Hartberg buys electricity on lower price levels and the produced electricity can be used locally)
  • Improvement of the time-wise distribution of the power flow (Stadtwerke Hartberg saves investments for the expansion of the network)
  • Usage savings for endusers (a higher level of sel-consumption and cheaper feed-in tariffs)

Reference project C: Research project „Das Proaktive Verteilnetz“

Challenges

The increase of renewable energies also increases decentralized volatile feed-ins into the power grid in the lower, medium and high voltage networks, which influences the system behaviour in an demanding manner. This evokes a more proactive role of the distribution system operator (DSO). At the moment there is no clear picture about the actual state of the distribution grid. The transparency and controllability of the net assets on the high voltage level is very good, however it is lower on the medium voltage level and practically non-existant on the low voltage level.

Traffic light concept (in German: “Ampelkonzept”) and the proactive role of the distribution system operator (DSO)

This research project follows the capacity traffic light concept, which is a German regulatory framework about the interaction between the distribution system operator (DSO) and the transmission system operator (TSO). This regulatory framework was first developed by the Federal Association of the Energy and Water Industry (in German “Bundesverband der Energie- und Wasserwirtschaft (BDEW)”). The framework describes the interlinkage between all actors of the market and regulatory side. It differentiates the interaction between market and power grid between the system status „green“, „yellow“ and „red“.
With in the green phase the grid mains operation is using the common market mechanisms. In the yellow phase grid congestions will be solved by preventively using existing flexibilities between grid- and market actors, which will be arranged in a non-discriminating way. Following, the existing degrees of freedom for relieving the load of the distribution and transmission grid are used by means of market and regulatory compliant system services (in German: “Systemdienstleistungen (SDL)”). Enforced shut-downs at the endusers side can be prevented as long as the market actors will find appropriate solutions during their negotiations to meet their delimited geospatial and time-distant net capacity demand according to the existing net capacity supply.

Within the research project, technical solutions will be elaborated and proven, which qualify the DSO to counteract in the case of possible congestions by using existing flexibilitites, which are provided by the market. This will contribute to the operational and supply security. As well, it will reduce investments in the grid expansion. The outcomes will be prototypical implemented in an actual system. It is the first time that a systemic approach about the development of an encompassing, state-based and cross-voltage level load, production and information management for distribution grids will be pursued. (please see the figure below).

Solution

The solution is the exploration of an encompassing, state-based and cross-voltage level load, production and information management for distribution grids by taking all market requests into account, which means the optimal cooperation of a “smart grid” and a “smart market”.
In order to provide actual input data, the project references to internal developments of Venios Energy Solution (VES). Venios Energy Solution (VES) allows the geospatial and time-resolved analysis of electrical energy systems. The system of Venios has been proven of being able to parallelly process different data sources and models („Big Data“). Besided the measuremnt-based detection of the net topology the projects includes the enhancement of analysis about the local production and usage by using secondary data sources.

Expected results

By having a situation-based and coordinative distribution control, the DSO will be qualified to playing a proactive role. This proactive role encompasses the following five aspects:
1. detection and analysis – especially in regards of monitoring currently unaccesible grid status at the lower and medium voltage level,
2. situative coordination between market players and grid operators by minimizing direct interventions at the same time,
3. usage of flexbilitites, which are within the competence of the DSO,
4. provision of system services by the DSO and
5. training the DSO to execute grid operations in an automated way.

Altogehter, in this project Venios Energy Solution (VES) contributes in the following way:
• Entrusted and manageable state estimations of the distribution grid
• Secure and non-discriminant coordination of market players and grid operators
• Semi-automated grid operations by the DSO, which is practically proven.

Reference project D: Stedin, Netherlands

 

Challenges

The increase of single PV-systems and their feed-in into the distribution grid stresses the power grid of the Netherlands, which will lead in the end to net capacity problems in the first hand. On the top of this, the upcoming trend of electric vehicles and charging stations in city areas drive the grid capacity to its limits (see Figure 1 below). Stedin in Rotterdam foresee the challenges along with this trend and take steps into actively managing the grid.

Figure1
Figure 1: Congestions in the distribution grid

Solution
The goal by using the Universal Smart Energy Framework (USEF) is to from flexibilities in order to solve upcoing problem zones in the distribution grid.
A central component in this solution is the employment of Venios Energy Solution (VES) in order to identify these flexiblities and making them available. VES contributes in two ways. First, it estimates the load and generation, which are additionally combined with measurement data. Secdond, VES predicts the load and generation as well as makes it possible to add or shut-down production capacities. In the end, VES also allows in the later stage of the project to integrate new measurement hardware, battery storage systems or controllable substations.

Implementation
Stedin already deployed VES in parts of its power grid. Due to the modular system of VES, the expansion on wider grid areas can be easily done. In doing so, the current system will be enriched by additional measurement data and grid information. Load predictions will be recieved and imported over USEF-interfaces and enriched by additional prediction information. This information are the input of a net security analysis. After this analysis, VES generates necessary information about flexibilities and sends this information to production assets, which are within the USEF-Framework.
An important aspect are data protection and data security. The information will be encrypted during the transmission. A data security system assures a secure data access and does not allow other parties accessing the system.

Expected results
The specific control and generation of flexibilities in terms of load and generation prevents congestions in the distribution grid. On the top of that, all players will be actively integrated into the system in order to generate flexibilities. The integration of electric vehicles, charging stations or battery systems into the distribution grid will be possible.
