Prosumers’ electrical installations (PEIs), as nanogrids and low-voltage microgrids, have gained importance in recent years following the development of standards such as the IEC 60364-8 series. In these systems, all distributed energy resources (DERs) are usually integrated using dc bus coupling. The IEC 60364-8-3 predicts an electrical energy management system (EEMS) for power-sharing. The overall research framework of this paper is the nanogrid power management, where complex algorithms are required, as well as the conventional state machines and hierarchical controls. However, the addition of new DERs in such systems is not straightforward due to the complicated parameter settings for energy usage optimization. A different control strategy, named price-based power management, has been conceived to make the EEMS scalable to include new sources and simplify parameterization. Since it is analogous to economic markets, most users understand the concepts and feel comfortable tuning parameters according to their own cost/benefits goals. This paper proposes a price-based power management algorithm for EEMS to automatically design the price-response matrices (PRMs). The PRMs are a way to organize power management, considering new DERs and variable price of energy. The main contribution is the methodology to design the PRMs. Experimental results are carried out to demonstrate the effectiveness of the proposed strategy. The results were obtained with a 1.5 kW prototype composed of a PV generator, battery energy storage, loads, and grid connection.

Conflicts can be dangerous or may even benefit a relationship, depending on how they are resolved. Because conflict creates strong emotions, emotions are not suitable as a basis for constructive problem solving. Conflict escalation rarely benefits a relationship, especially if it creates selfishness, stubbornness, and withdrawal from relationships. What's worse, conflicts can lead to physical disputes and actual violence, a community can work together, but it can be that at other times the community that has worked together can turn into social conflict. Conversely, people who initially conflict can change to work together for a certain time. For that social processes that occur are very dynamic, these conditions are very dependent on the power management model that runs in the community concerned thus interpreting the conflict based on the causes of conflict are: specific behaviors, norms and personal roles and dispositions. Conflict can also occur in the name of religion, caused by several factors including: superficial religious knowledge, fanaticism, religion as a doctrine, symbols, religious figures, history, fighting for surge.
