The challenges of the power systems are becoming more difficult to deal with especially because of the increased renewable energy installations. For more reliable power systems, the grid operators and the component manufacturers have to make more detailed and accurate analyses than in the past. Lean Power Solutions presents faster and more reliable network analysis software which is designed to easily solve the increasing challenges power system operators are more and more encountering. Our user friendly software tool LPS DSim helps to calculate and analyze complex power systems in a faster and more accurate way:
LPS DSim is an innovative multi-physics software program for the calculation of the steady-state and the dynamic behavior of physical systems. Different physical systems can be calculated together in the same data set, too – for example electro-mechanical such as a power plant or an e-car.
Every system under consideration is represented as a network, topologically defined as a (connected) graph, i.e. a construct of nodes and branches connecting the nodes such that for every node pair a path between them exists.
LPS DSim has been designed for general networks and implements a specific interface for the network components. The solving algorithm needs only that every network component complies with the component interface but it makes no further assumptions regarding how the component is internally modeled. The number and kind of components in LPS DSim library can be thus optionally extended.
A possible list of the systems which could be represented and calculated by LPS DSim follows:
- electrical networks
- pipe networks (water/gas/steam)
- mechanical systems;
- civil structures (as buildings, bridges, highways);
- thermal processes;
- urban traffic networks;
- biological multi-cellular systems;
- economic systems including finance markets.
An important skill of the LPS DSim algorithm is the use of concurrency. At present, well-known commercial packages do not allow multi-core steady-state or dynamic calculations. However, the trend in high-performance machines is to increase the number of CPU cores as the growth of speed is limited. Therefore, most commercial packages would not take significant advantages from this trend. On the contrary, LPS DSim has been conceived from the beginning to be able to use the full power of multi-core calculations.
