A microgrid is defined as a small-scale local grid, comprised of various distributed energy resources (DERs), loads, and energy storage systems. Due to the intermittency of renewable generation, microgrid controllers play a vital role maintaining microgrid stability and integrity in case of an energy shortage (surplus) or when subjected to any disturbances. These controllers should be designed to provide proper control of voltage and frequency. Supervisory controllers are high level control systems that perform optimization, faults detection, protection, and energy management based on their observation from the microgrid. Supervisory controllers define set points to the local controllers for DERs and loads. In this paper, the joint continuous and discrete behavior of the supervisory controller is addressed using a hybrid controller. A complete model of the hybrid automaton (HA) is formalized and tested through one case study of a microgrid using DIgSILENT PowerFactory software. According to the results, the controller can thoroughly manage the load flow within and outside the microgrid.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123341718","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}

Remedial Action Scheme (RAS), widely used for wide area protection, provides autonomous operations through the RAS controller. Due to its dependence on the timely cooperation of multiple devices and communication network, it is highly vulnerable to cyber attacks. In this paper, we present an impact analysis for the power system due to a class of malware-based coordinated cyber attacks targeting the RAS scheme. Specifically, we make the following two contributions. First, modeling a stealth attack vector based on malware and coordinated attack behavior. In particular installing the malware (Trojan horse) in the RAS controller which turns the controller into an attacker's bot. Then, performing a coordinated attack which involves malicious tripping of one of the parallel lines connected to a generator followed by the continuous pulse attack on the generator. The pulse attack includes periodically changing the generations through RAS controller which remains undetected by the control center. Second, testbed-based implementation and evaluation to quantify system impacts. We have leveraged Iowa State's PowerCyber CPS security testbed for experimental evaluation. In our evaluation, we varied the duty cycle of the pulse attack to obtain different attack scenarios and consequent impacts are analyzed on modified IEEE 9-bus system in real-time simulation. Our studies show that the duty cycle of the pulse attack is a critical factor in determining the severity of the attack impacts on system stability.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"15 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113954582","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}

Charging EVs can present undesirable effects, e.g., overload components, in the distribution systems. In the proposed TE+TC approach, the distribution system operator (DSO) generates a distribution locational marginal price (DLMP) for the transactive nodes (TNs) which is then sent to each customer's house, assuming that the TN and the customers have local agents. Based on their needs and the received transactive incentive signal (TIS), consumers will determine their EVs charging hours. Upon execution, the consumer sends the information back to the transformer as a transactive feedback signal (TFS). This information allows the DSO to recalculate its TIS at the TN and adjust the new demand pattern accordingly. In order to evaluate the effectiveness of the proposed TE+TC approach, this paper considers a case study of a transformer located at a 6-bus distribution feeder test system.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116476281","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}

Currently, wind and solar energy resources have the highest rates of growth, and specifically in the recent years, solar energy has been number one in growth rate among all types of renewable resources. However, dealing with the solar energy's intermittent nature is the main challenge of its utilization. Fluctuations of received solar irradiance can cause significant variations to the output of Photovoltaic (PV) systems. Those output variations can also affect voltage and current at the Point of Common Coupling (PCC) and consequently, power quality of the system. In this work, fluctuations of a PV system due to a cloud shadow are simulated and their effects on Total Harmonic Distortion (THD), and Individual Harmonic Distortion (IHD) during the period in which the cloud shadow passes over the PV system are studied. Simulations results show that decrease in received irradiance caused by the cloud shadow can significantly impact the current THD of the system. Moreover, the effect of the impedance between the utility grid and the PCC on voltage THD is assessed.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114581709","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}
