| Abstract |
A strategy for managing active distribution systems (ADS) requires the use of optimal control techniques that find a good solution to reduce active power losses. The solution to this type of problem presents two major difficulties: on the one hand, the optimisation problem is generically formulated as a mixed-integer nonlinear propagation problem, whose solution requires a high computational cost and, on the other hand, its application to complex distribution networks, which are characterised by their radial nature, large number of busbars, long length, and significant imbalances due to the presence of loads distributed unevenly between the phases. This chapter presents the development of an economic dispatch (ED) optimisation model for active distribution system management (ADSM). In this context, DIgSILENT Power Factory® provides useful tools to simulate complex systems. On the one hand, the DIgSILENT Programming Language (DPL) can be used for multiple purposes such as automation of simulations, automatic scenario generation, analysis of results, etc. On the other hand, DIgSILENT Power Factory® supports some external interfaces that can be used for data exchange and coupling with MATLAB®. The control and optimisation strategy are validated in IEEE 34-Node Distribution Test Feeder. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |
