Regional integrated energy system (RIES) can realize multi-energy conversion and complementation so as to improve energy efficiency, which also brings more security risks. The regional integrated energy system security region (RIESSR) is a security analysis method to describe the safe area for the operating points of RIES based on the N-1 guideline. As a controllable device, energy storage (ES) which is installed in the energy hub (EH) plays an important role in improving system security. Therefore, this paper establishes the model of practical security region of RIES integrating energy storage, and studies the impact of ES on total supply capability (TSC) and practical security boundary. Finally, a specific case is set to simulate and verify the model. By comparing the scenario with ES and the scenario without ES, it can be seen that the solution result of TSC increases and the security region extends across quadrant when the RIES is integrated with ES system. The capacity and location of the ES also impact on TSC and RIESSR.

Os Sistemas Elétricos de Potência estão evoluindo de um modelo centralizado de geração para uma complexa infraestrutura com recursos energéticos distribuídos. As mudanças transformadoras são especialmente observadas no nível dos sistemas de distribuição, com o surgimento de novas tecnologias que afetam o perfil de consumo e geração própria dos clientes, o planejamento e as operações dos serviços públicos de distribuição de energia. Assim, o principal objetivo deste trabalho é apresentar uma nova ferramenta para análise de segurança em sistemas de distribuição com presença de recursos energéticos distribuídos. A ferramenta proposta irá auxiliar na operação, planejamento e gestão dos sistemas de distribuição e, consequentemente, na melhoria da qualidade dos serviços prestados pelas concessionárias de distribuição. Esta ferramenta é desenvolvida na linguagem Python e utiliza o programa OpenDSS como ferramenta de solução de fluxo de potência.

Summary This paper applies the geometrical observation of security regions in distribution network enhancement. Firstly, the concepts of distribution system security region (DSSR) and total supply capability (TSC) curve are introduced. Secondly, to observe DSSR and TSC more intuitively, new geometrical shape figures of DSSR such as the spiral figure of the region, the radar figure of boundary, and the concave figure of the boundary are proposed. New geometrical indexes, such as radius of DSSR, area of shape figure, shape distortion indexes and concavity indexes are also proposed. The proposed indexes and figures can fully describe the security and efficiency of a given distribution network from the perspective of the size and shape of DSSR. Thirdly, the indexes family are proposed, and the concrete method of the distribution network enhancement is presented based on the indexes family. Finally, the expanded IEEE‐RBTS‐BUS4 case is used to verify the proposed method. The results show that the proposed method can intuitively show the changes of the enhanced distribution network in the terms of DSSR and TSC curves. This paper proposes a new observation method and analysis tool for the distribution network from the perspective of security and efficiency, which is an important supplement to the traditional enhancement of the distribution network.
