Daytime solar power generation peaks necessitate demand-side flexibility to mitigate voltage dips and spikes that could disrupt the power grid. To this end, a model-free demand response framework is developed based on deep reinforcement learning (DRL) and using OpenAI Gym APIs. The DRL agent assumes the role of a load aggregator that directly controls a percentage of each load in the distribution system. The agent is then trained to optimize the control policy by taking nonuniform actions on each node. The system-wide objective is to minimize the voltage deviations from 3% of the nominal voltage in an effort to properly allocate the energy consumption throughout the day. The DRL-based demand response is trained and tested on the radial IEEE 33-bus distribution feeder, modified to have a high penetration of non-dispatchable PVs plants. Simulation results show that the proposed framework works as intended, shifting flexible demand to times of maximum solar power generation while maintaining an acceptable voltage deviation at each node.","PeriodicalId":206589,"journal":{"name":"2022 Saudi Arabia Smart Grid (SASG)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115483014","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 DERs considered in this research comprise distributed renewable energy resources (RESs), distributed thermal generators (TGs), and battery energy storage system (BESS). Furthermore, the proposed model incorporates coordination between the DSO and the water desalination operator (WDO) in the operation aspect to investigate the effects on the optimal sizing and location of DERs as well as the overall profits to the DSO. The proposed model is validated using a 38-bus radial distribution network. Simulation results indicate that considering coordination increased the overall profits to DSO by 6.8%. Moreover, without coordination, additional BESS is required to be installed in the bus where WDFs are located to smooth the electric load profile. However, the coordination eliminates the need for installing BESS as the coordination can smooth the electric load profile by managing the desalination operational schedules.","PeriodicalId":206589,"journal":{"name":"2022 Saudi Arabia Smart Grid (SASG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131007986","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}

Many AC power transmission and DC transmission lines are constructed to meet large capacities worldwide. Traditionally High Voltage Alternating Current (HVAC) transmissions have been used for power transmission worldwide in the last century. High Voltage Direct Current (HVDC) technology has specific characteristics which make it unique for transmission system applications, such as long-distance transmission and submarine cable crossings. Studying all types of faults is necessary to protect the design and keep the grid healthy because the faults will significantly impact the transmission system’s operation. This work aims to study the impact of the faults at the proposed transmission line between Central and Western regions in the Kingdom of Saudi Arabia, as well as the feasibility of the project by deep research into the background of the HVDC system and fault analysis at the DC transmission system, which results in knowledge of the impact on the grid before and after the faults occur. The proposed work is modeled and simulated using PSCAD software to simulate the faults on the HVDC transmission line. The results were also analyzed and studied.","PeriodicalId":206589,"journal":{"name":"2022 Saudi Arabia Smart Grid (SASG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128320743","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}

It can be operated independently or in coordination with the national utility grid of a country. Microgrid operators face different operational challenges and uncertainties while meeting the electricity demand of their customers. This research aims to develop a community microgrid (CMG) energy scheduling strategy considering the electricity price, renewable generation, and load demand uncertainty. The considered CMG system is connected to a utility grid and comprises of a solar photovoltaic (PV) plant, a wind generation system, a micro-turbine, an energy storage system (ESS), and a lumped load. A versatile mathematical optimization problem is formulated and solved using an efficient meta-heuristic technique called the whale optimization algorithm (WOA). The proposed strategy combines an intelligent control system with management software to track the CMG customers’ energy requirements and meet the demand with minimal cost by optimizing the available resources. The findings from the research verify the utilization of the ESS in the microgrid to reduce the overall operating costs.","PeriodicalId":206589,"journal":{"name":"2022 Saudi Arabia Smart Grid (SASG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131283659","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 Saudi power grid full model in PSS/e is significantly reduced using the DYNRED tool while preserving the desired dynamic features. Then, the reduced model is converted from PSS/e format to RTDS format for real-time simulation. The WADCs are designed using a measurement-driven approach and integrated into the RTDS model, with the generator units (ex-citer and governor) in three selected power plants as the actuators. Finally, the WADCs are tested in the RTDS model under various contingencies, including an actual incident of a large amount generation trip that occurred in 2017 and resulted in system separation. The test results demonstrated that these WADCs can prevent the entire system from separation after large generation trip disturbances. Meanwhile, these WADCs can further enhance the power transfer limit of the tie-lines between the operation areas in the Saudi power grid.","PeriodicalId":206589,"journal":{"name":"2022 Saudi Arabia Smart Grid (SASG)","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131591726","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}
