DC microgrid is becoming popular because of its high efficiency, high reliability and connection of distributed generation with energy storage devices and dc loads. The main objective in the dc microgrid is to keep the dc bus voltage constant and equalise per unit current sharing among converters. The conventional droop control is used to equalise per unit current sharing similar to reactive power sharing in an ac microgrid. Nevertheless, the problem in conventional droop control is that equal current leads to a reduction of dc bus reference voltage and voltage regulation becoming unequal across each node due to unequal line resistance drop. The proposed controller works on adaptive droop and voltage shifting technique, which equalises the current sharing whether line resistances are similar or not and controls each output voltage to follow the respective bus reference voltage. The isolated dc-dc converters are used to simulate and validate the proposed control technique.
Abstract. Background: Understanding and effectively managing self-harm and suicide require collaborative research between stakeholders focused on shared priorities. Aims: We aimed to develop a consensus about suicide and self-harm research priorities in the North West of England using the Delphi method. Method: Items for the Delphi survey were generated through group discussions at a workshop with 88 stakeholders and subsequent thematic analysis of key themes. A total of 44 participants who were experts-by-experience, researchers, and clinicians based within health services including third-sector organizations completed the Delphi survey. Results: A three-round survey reached consensus on 55 research priority items identifying key priorities in each of the following groups: offenders, children and young people, self-harm in community settings, and crisis care in the community. Limitations: The pool of delegates at the workshop and subsequent self-selection into the Delphi may have introduced bias into the study. Conclusion: The current paper highlights specific actionable priorities were identified in four areas that can be used to inform research efforts and future policy and practice, based on shared areas of perceived importance and concern. Future work is needed to confirm the significance of these priority areas, including the use of evidence synthesis approaches to ascertain the extent to which these priorities have already been investigated and where gaps in understanding remain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
