(Robot) swarm networks are consisting of magnitudes of individual agents that are capable to move in a world and interact with each other or with passive items. Through local, individual algorithms applied in the agents desired properties of the swarm can emerge. In this paper, we present Swarm-Sim, a round-based simulator that supports the evaluation of such large scaled swarms in a 2D and 3D world. Agents can move in the simulated world, perceive their surroundings, carry other agents and items, as well as communicate with the position they stand on through pheromones or markings as well as with other agents and items in this world. Through this, many swarm-related use cases are supported. Implementing swarm algorithms is easy as the simulator is completely written in python and its code is open source. This allows also to simulate large swarms due to the good performance of the simulator. Thorough analysis of the swarm behavior is supported through plots and visualizations.

This paper presents integrated controlalgorithms for a single-phase line-interactive transformerless bidirectional buck-boost Uninterruptable Power Supply (UPS). The controlalgorithms consist of two battery controlalgorithms and one dc to ac conversion algorithm. The battery controlalgorithms are applied to a bidirectional buck-and-boost converter. Additionally, an AC/DC-DC/AC converter employs the dc to ac conversion algorithm. The battery controlalgorithms utilise two Proportional-Integral (PI) controllers to regulate voltage and current, respectively. In contrast, the dc to ac conversion algorithm applies one PI voltage controller and a bandless hysteresis current controller. The battery reference value is set according to the battery's fully-charged voltage for the battery charging control algorithm. Meanwhile, the dc output voltage is set higher for the battery discharging control algorithm to allow the success of dc to ac conversion by the AC/DC-DC/AC converter. Based on the simulation findings, both independent controlalgorithms can govern the functioning of both converters in both modes of operation. Consequently, the UPS system can supply sinusoidal voltage and current waveforms with low Total Harmonic Distortion (THD) output.
