The need for everyone to participate in sustainability is accepted globally vis-a-vis technological advancement, political and environmental regulation. Weather, which is a major metric of global warming, has an unsustainable close cycle correlation with the energy industry. For instance, the use of power plants that aren't designed for extreme weather conditions leads to unwanted grid outages. This grid outage usually has severe effects on the life, health, and livelihood of the people in the environment. A typical situation is an occurrence in Texas in 2011 and the recent one in 2021. However, mitigating against this challenge is also a major concern as their occurrence aren't frequent enough and cannot be easily forecasted, hence; there is a need for an effective cost-driven solution to be implemented, such that all the stakeholders in the electricity value chain can benefit optimally, in terms of profit and from a social welfare perspective.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130758351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With thousands of devices and various adversaries, it is hard to assess the impact of those devices under adversaries on power systems. The lack of enough situational awareness can lead the operators to misunderstand the system and make inappropriate decisions. Thus, this paper presents a framework to consider different types of contingencies for a comprehensive device-oriented risk assessment. The proposed framework considers three aspects, including the Steady State Contingency, Transient State Contingency, and Device Model Validation. Corresponding metrics have been utilized to evaluate the power system elements with respect to power system security. With the input information, the proposed framework streamlines and automates the process of quantifying the risk of different devices through different types of contingency analyses and metrics. In this way, operators can get comprehensive situational awareness to ensure the security of the system and avoid potential cascading failures. This paper uses the synthetic 200-bus case (ACTIVSg200) to illustrate the process of quantifying cyber-physical risk using the proposed framework.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129984966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are different standards to maintain power grid bus voltages within the desired threshold limits. In this paper, different international settings are normalized in consideration of USA power grid limits, and these normalized settings are applied to Volt- Var control of smart PV inverters. The selected parameter settings for Volt- Var control are investigated using a modified IEEE 13 bus system as the case study. To evaluate the system performance under each condition, a real time simulation model is developed using Typhoon Hardware In Loop (HIL). The simulation results verify that different features (size of dead-band, voltage limits, absorbing/injecting amount of reactive power) of Volt- Var control plays a critical role in voltage regulation under high PV penetration conditions that have to be carefully considered at design and operational stages.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126749829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of incorporating different graph embeddings on outage risk prediction is evaluated. The method used for graph embeddings is N ode2Vec. The grid search is performed to find optimal hyperparameters of N ode2Vec. The resulting accuracy metrics for a set of different hyperparameters are presented.

In this work, several forms of cyber stresses on power system's measurements and state estimation have been analyzed using the local smoothness of their graph signals. Using the local smoothness, characteristics of different cyber stresses are described analytically and evaluated by simulations.

However, increased resiliency also requires these microgrids to collaborate intelligently. Collaborative actions among microgrids requires algorithms to operate the network optimally. These algorithms require reliable communication networks to operate. The nature of the communication network plays an indispensable role for feasible operation of the power system and collaboration among microgrids. In this paper, we employ a fast distributed optimal power flow (D-OPF) algorithm with different communication network topology to demonstrate the impact of communication network and properties on collaborative microgids to attain optimal operations of the power distribution grids. This paper provides insight on how cyber complexity impacts the D-OPF method and the power system it controls.
