The strategy employs an energy management approach that considers the price sensitivity of EV drivers. Three priority groups are specified based on the EV’s state of charge (SoC) level: high-priority, low-priority, and normal-priority. Different time slots for charging are offered to drivers at varying prices, designated as red, blue, and green time zones. The proposed approach begins with a power flow program that checks all constraints before an EV can be permanently placed on a charging node. An objective function is formulated to minimize production costs while ensuring that the constraints on bus voltages and maximum allowed power consumption are met. Simulation results demonstrate the validity of the proposed algorithm in shifting loads while satisfying all network and EV constraints.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114332323","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}

As a result, microgrids (MGs) with renewable energy integration and charging facilities have attracted significant attention. Nonetheless, disregarding uncertainties in optimization models for MGs can lead to either risky or costly decisions. In addition, sustainable development and operation of MGs must enhance the system’s resiliency to guarantee functionality during abnormal situations. Therefore, this paper proposes a two-stage stochastic programming model to ensure the resilient operation of microgrids with charging facilities. At the same time, uncertainties associated with renewable generation, demand, and market price are addressed via scenarios. To enhance resiliency against unplanned islanding, a scenario for outages is defined so that preventive actions can be done in the first stage to robust the energy management of the microgrid.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"301 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116600364","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}

This paper assesses the power system stability: frequency and angle stability for Integrated Nepal Power System (INPS). The INPS modeled in this study consists of 24 machines, 58 buses, and 77 sections of the transmission line. The network components, generators, excitation systems, governor systems, etc. are first modeled and different stability indices related to the frequency and rotor angle stability of the power system are calculated using DIGSILENT PowerFactory. The frequency nadir and the Rate of Change of Frequency (RoCoF) are two indices used for determining the frequency stability, and eigenvalue, damping ratio, critical clearing time, and transient stability indices are used for angle stability assessment in this paper. The simulation results show that Mistri Khola hydropower and Chilime hydropower are most critical with respect to frequency stability due to the lowest frequency nadir and high RoCoF respectively. Similarly, Kaligandaki-A hydropower station is the most critical with respect to the system damping. Furthermore, the performance of the Battery Energy Storage Systems has also been analyzed and are found to improve the system frequency nadir and reduce RoCoF.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123304514","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}

For this purpose, an optimization model is proposed considering the investment and maintenance costs of the parking lots as well as the operation and emission costs of microgrids. In the model, natural gas and electricity distribution systems are simulated in a grid-connected microgrid with a considerable share of wind turbines. A scenario generation technique is also utilized to determine the number and arrival state of charge of electric vehicles in parking lots. A microgrid, which consists of a 33-bus electricity system and an II-node gas system, is studied to investigate the charging and discharging of electric vehicles in parking lots. It concludes that electric vehicles in parking lots offer flexibility that offsets investment costs and reduces the amount of emission. Owing to the flexibility, the natural gas system can also respond the changes in natural gas demand more efficiently due to more natural gas within pipelines.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128060816","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}

This issue is targeted in this paper, and using a buck-boost balancer is tried to mitigate the problem. To this end, the state space model of the bipolar DC microgrid and the voltage balancer converter is extracted, and considering its nonlinear dynamic, the feedback linearization technique is applied to improve the voltage and power balance.

To fully exploit the regulation capacity of energy storage, a novel dynamic sharing business model for the user-side energy storage station is proposed, where centralized capacity sharing and peer-to-peer (P2P) transactions of scheduling right are considered. The business model can be described as a two-stage game process, where the Stackelberg game is firstly carried out between shared energy storage (SES) and prosumers to transact leasing capacity of energy storage, and a non-cooperative game is conducted among prosumers to further share the charging and discharging scheduling right. Considering the behavior of prosumers, a bi-level model is formulated to realize the interaction between SES and prosumers. The upper-level SES sets the leasing price of storage capacity to prosumers with the goal of maximum profits, while the lower-level prosumer provides leasing capacity and power schedule to SES. Besides, prosumers trade peer-to-peer scheduling rights between them. Such a Stackelberg game with one leader and N followers is an NP-hard problem and challenging to solve. A generalized Nash equilibrium solution method based on the Karush-Kuhn-Tucker (KKT) conditions with approximations is proposed for solving the solution of the business model. The case study verifies that the user-side energy storage business model proposed in this paper has a more considerable profit margin than the traditional fixed capacity sharing model and effectively improves the efficiency of idle energy storage utilization.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129739384","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}
