Companies that can supply or accept energy at short notice can achieve good prices on electricity markets. A new solution from Siemens links smart data with smart grids so that many different facilities can be combined to trade electricity flexibly.
Thanks to a new virtual power station from Siemens, companies can fully exploit the business opportunities offered by short-term trading on electricity markets on timescales as short as less than one hour. Siemens’ solution enables operators to combine conventional power plants, industrial facilities, and renewable energy producers on a large scale via EnergyIP, a smart grid data platform. Generation and availability data of all associated facilities are collected on this platform so that very detailed forecasts of the total amount of tradeable energy can be made. At the same time, EnergyIP provides the software applications needed to process electricity trading. These applications include a price forecasting feature as well as a system for handling billing between participants.
Small Grid Operators Welcome
Because the solution enables power suppliers to handle large numbers of facilities and obtain very precise forecasts, they can also achieve optimal results during short-term trading. Moreover, the solution gives small grid operators, renewable energy producers, and industrial companies access to the electricity trading market, where they can sell their surplus electricity. It enables steel mills, for example, to generate and sell extra electricity from surplus coke oven gas. Such a new-generation virtual power plant could, for example, be operated by a major energy supplier that combines its large and small facilities so that it can manage them from a central location or offer electricity trading as a service to other market participants. Another possibility would be to create a cloud-based solution.
Such a solution will become necessary in the future because electricity trading is shifting to short-term electricity markets. Until now, electricity has been traded for periods ranging from a few months to one or two years. However, competition on free electricity markets and the expansion of renewable sources of energy are now causing prices to fluctuate substantially. This volatility can be exploited if a trader acts very quickly on the market. To do this, however, market players need solutions that directly integrate current and forecast generation and demand data into trading processes.
Production Data and Business Processes in a Single System
The new virtual power plant from Siemens can do precisely that. It links Siemens’ Decentralized Energy Management System (DEMS) with its EnergyIP data hub. DEMS can combine several renewable energy producers to form a virtual power plant. Participants transmit their availability and generation data to the platform, which uses this information to make forecasts for the total amount of energy available. This is then used as a basis for trading electricity on a separate system. In addition, DEMS enables all of the facilities to be managed from a central location. However, until now, the number of participants in such systems was limited. In order to change this and integrate generation data directly into the electricity trading processes, DEMS was ported to the EnergyIP platform.
The latter consists of distributed servers that collect and process meter and measurement data. This pool of data is used by software applications to handle business transactions for electricity and other, similar goods. Examples include a customer’s change in suppliers, the billing of grid use between a grid operator and an electricity supplier, and the billing of facilities that are integrated into a virtual power plant. EnergyIP can handle tens of thousands of participants and process the huge amounts of data that will be collected in the future when smart meters will sometimes transmit measurements at intervals as short as 15 minutes.
Another important factor is the ability to securely conduct business transactions solely between the respective partners in a process that experts refer to as role and authorization management. In addition, this new solution can easily integrate additional participants, making it profitable for many small electricity suppliers as well. The combination of EnergyIP with DEMS has created a platform that brings thousands of electricity suppliers and their generation data together and enables them to operate on the electricity market securely and quickly on the basis of reliable forecasts and business processes.
