Narratives of Spatial Division： The Role of Social Memory in Shaping Urban Space in Belfast

The paper examines the role of shared spaces in divided cities in promoting future sustainable communities and spaces described as inclusive to all. It addresses the current challenges that prevent such inclusiveness and suggests future trends of its development to be of benefit to the wider city community. It explains how spaces in divided cities are carved up into perceived ownerships and territorialized areas, which increases tension on the shared space between territories; the control of which can often lead to inter-community disputes. The paper reports that common shared space in-between conflicting communities takes on increased importance since the nature of the conflict places emphasis on communities＇ confidence, politically and socially, while also highlighting the necessity for confidence in inclusion and feeling secure in the public domain. In order to achieve sustainable environments, strategies to promote shared spaces require further focus on the significance of everyday dynamics as essential aspects for future integration and conflict resolution.

Optimal Planning of Community Integrated Energy Station Considering Frequency Regulation Service

With the extensive integration of high-penetration renewable energy resources,more fast-response frequency regulation(FR)providers are required to eliminate the impact of uncertainties from loads and distributed generators(DGs)on system security and stability.As a high-quality FR resource,community integrated energy station(CIES)can effectively respond to frequency deviation caused by renewable energy generation,helping to solve the frequency problem of power system.This paper proposes an optimal planning model of CIES considering FR service.First,the model of FR service is established to unify the time scale of FR service and economic operation.Then,an optimal planning model of CIES considering FR service is proposed,with which the revenue of participating in the FR service is obtained under market mechanism.The flexible electricity pricing model is introduced to flatten the peak tieline power of CIES.Case studies are conducted to analyze the annual cost and the revenue of CIES participating in FR service,which suggest that providing ancillary services can bring potential revenue.

Community Integrated Energy System Trading:A Comprehensive Review

Focused on life,consumption,and leisure,communities have been regarded as the basic unit of energy use in a city owing to rapid urbanization,whose energy use density continues to increase.Moreover,community integrated energy systems(CIESs)in the rapid development stage have become embedded,small,and self-sufficient energy ecosystems within cities because of their environmental and economic benefits.CIESs face a competitive energy trading environment that comprises numerous entities and complicated relationships.This paper presents an extensive review of various issues related to CIES trading.First,the concepts,types,and resources of CIESs are described.Second,the trading patterns and strategies of CIESs are reviewed from the four perspectives of the trading objects:community-to-peer(C2P),peer-to-peer(P2P),community-to-community(C2C),and community-to-grid(C2G).Third,a tri-layer trading framework and the features of CIESs that participate in combined multienergy markets are proposed.Last,the key issues in CIES trading are summarized.

Northeast Asian Community Building: What Needs to Be Done?

The aim of the Northeast Asian community building is to create an environment for living together peacefully and for realizing prosperity through cooperation. Economically, a community will integrate regional economies and share great interests for common prosperity. Politically, a community will stabilize the region with trust and cooperation. In terms of security, a community will realize the lasting peace of the region. The three economies of China, Japan, and the ROK account for a vast majority of Northeast Asia＇s regional economy. China and the ROK are two key players in the Northeast Asian community building. China-ROK cooperation will be helpful for China-Japan relations that now appear to be in a difficult situation. Northeast Asian economic cooperation has developed into a multi-layered structure both in institutional and non-institutional ways. In order to build the Northeast Asian community, those three countries must first improve and make three close bilateral relationships. However, Northeast Asian community building should not just include China, Japan, and the ROK. The DPRK, Mongolia, and also Russia should be engaged as early as possible. Northeast Asian community is a vision and also a dream that needs great efforts to be realized by both a good spirit and real actions.
