A continuum model proves to be effective in capturing Electromechanical Wave (EMW) propagation characteristics, including its velocity, arrival time, and deviations. Analyzing these characteristics enables the assessment of the impacts of EMW on the performance of the protection system. Prior research has often modeled nonlinear EMW propagation through Partial Differential Equations (PDEs) within a homogeneous and uniform frame structure, assuming constant bus voltages across the entire power system. However, this assumption can produce inaccurate results. In this paper, we relax this assumption by introducing a second-order nonlinear hyperbolic EMW propagation equation model that accounts for voltage variations. Additionally, we present numerical solutions for the EMW propagation equation using the Lax-Wendroff integration method. To validate our approach, we conduct simulations on two test systems, namely, a 5-bus 5-machine system and the New England 39-bus 10-machine system. The simulation results demonstrate the effectiveness of our proposed model and emphasize the importance of including the bus voltage equations in the analysis.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 4","pages":"1754-1765"},"PeriodicalIF":5.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11595370","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148749317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to power imported via HVDCs, many synchronous generators have been shut down in receiving-end grids. Under this circumstance, simultaneous commutation failures (CFs) of multi-infeed HVDCs are likely to occur under AC faults that may cause a blackout. Thus, it is crucial to enhance dynamic var support in receiving-end grids. Many studies mainly focus on fast action of power electronic dynamic var sources and synchronous machine (SM) AVRs' control, while spontaneous var output (SVO) of SMs may be underestimated. However, due to time delay of power electronic and AVR control, initial CFs are still likely to occur under short-circuit faults. To address this problem, this paper analyzes the mechanism of SVO and its impact on initial CFs. Then, the concept of Volt-VAR secure operational range (VVSOR) is proposed to ensure sufficiency of SVOs for preventing initial CFs. An optimization model for evaluating the VVSOR is established accurately without iteration with time-domain simulations. A heuristic solution method based on the decomposition algorithm is proposed. Finally, validity and efficiency of the evaluation method are verified based on a modified IEEE 39-bus system and a real system in eastern China.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 4","pages":"1809-1819"},"PeriodicalIF":5.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10165675","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148749204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To quantify the relationship between forecast errors and transmission power, a customized loss function is designed, embedding the operational dynamics of the REPP.

Different allocations of renewable energy sources (RERs) and flexible power-adjustable devices (FPADs) in VPP have different impacts on system strength. Short circuit ratio (SCR) is an important index used to assess the grid strength. First, this paper proposes an integrated short circuit ratio (ISCR) index based on the network structure characteristics of the VPP grid-connected system (VPPGCS). The ISCR considers the interactions among FPADs in addition to the interactions of the RESs in VPP to assess system strength accurately. Then, a bi-level optimal allocation method for RESs and FPADs is proposed based on the proposed ISCR to enhance system strength and increase the output capacity of VPP. In the upper level, the location and capacity of RESs are optimized. It guarantees the maximum value of ISCR at connection points (CP). In the lower level, the location and capacity of FPADs are optimized. It ensures the ISCR value is above the critical short-circuit ratio (CSCR) to maintain the system strength. Location optimization is determined by the ISCR value at CP. Capacity optimization is solved using linear programming. Finally, case studies verify the effectiveness of the proposed optimization method in increasing VPP output capacity while maintaining VPPGCS strength.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 4","pages":"1940-1951"},"PeriodicalIF":5.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10520147","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148746925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper extends the concept of unreliability tracing to power systems with high penetration of wind power, to realize unified allocation of load shedding to conventional generating units and wind power. First, a quantitative evaluation model for load shedding is established, which considers unreliable factors, such as failures of components, fluctuation, and intermittence of wind power. Then, load shedding at a certain time is decomposed into the part due to remaining unreliable factors that happened before the last time and the part due to unreliable factors that happened between the last time and the certain time, by decomposing the load shedding formula. Next, for parameters of the second part of the load shedding formula, unreliable factors that caused the value of these parameters to be located in regions leading to load shedding are decomposed into two parts in time sequence. The second part of load shedding is also decomposed into two parts corresponding to the decomposed unreliable factors. According to the decomposition of unreliable factors, two criteria for judging whether the component is responsible are extracted. Finally, the last two parts of load shedding are allocated to each component based on assumed baseline values of these criteria for each component, and the first part of load shedding is allocated, recursively. Several systems, including a modified provincial power system, are used to validate the rationality and validity of the model.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 4","pages":"1874-1886"},"PeriodicalIF":5.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10106202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148749029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along with development of IES, coordinated operation is necessary to further improve general efficiency of the IES cluster. Conventional distributed optimization methods are difficult to coordinate to optimize IES cluster operation, considering the balance of computational time, convergence performance, and initial value determination. This paper proposes a coordinated optimal dispatching approach for the IES cluster based on improved deep reinforcement learning. First, a distributed scheduling framework of the IES cluster with a cluster energy coordination center (CECC) as the upper coordinator and several area energy management centers (AEMCs) as the lower managers is introduced. Then, the energy interaction model and pricing strategy in the IES cluster that can facilitate multi-energy transactions are established. Finally, an improved multi-agent deep deterministic policy gradient (MADDPG) algorithm with a compression mechanism of initial state space is proposed for the model solution. Results show that compared with the conventional distributed algorithm of the alternating direction method of multipliers (ADMM), the improved MADDPG increases solving speed by 40 times while guaranteeing convergence and optimality of the solution. Besides, after considering energy transactions among IESs in the cluster, the total operating cost is reduced by 9.74%, and the self-sufficient ratio is raised to 0.92, reflecting the necessity of energy complementarity.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 4","pages":"2086-2105"},"PeriodicalIF":5.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10165673","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148746970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This evolution further affects the static voltage stability (SVS) margin value determined by the maximum load growth parameter. The SVS margin (SVSM) can be calculated based on the optimal power flow (OPF) method. The uncertain injected bus power and non-convex extended power flow equation constraints make the OPF model of SVSM calculation difficult to solve. To address these problems, an uncertainty-aware model (UaM) is established to identify the convex relationship represented by the uncertain non-convex extended power flow equations when the load growth parameter reaches SVSM. Based on historical data samples of the system, the UaM model establishes a training model to obtain a new convex relationship. By proposing an improved relaxed least absolute shrinkage and selection operator (LASSO) regression, the calculation efficiency and accuracy of the UaM-based training model are improved. Case studies on IEEE 14, 39 and 118-bus systems indicate that the UaM-based training model can capture the uncertainties of injected bus power to reduce the influence of RES power's predicted errors on the calculation results. The proposed improved relaxed LASSO regression can increase the calculation efficiency of the SVSM result compared with the regular regressions.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 4","pages":"1778-1790"},"PeriodicalIF":5.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10684472","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148747091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel deep reinforcement learning algorithm, the Relative Entropy Regularized Asynchronous Update Soft Actor-Critic algorithm, to address these challenges. First, the algorithm compensates for missing data during communication interruptions using predictive modeling techniques, thereby ensuring continuous and accurate system operation. Then, to handle the challenges posed by prediction errors, a relative entropy regularization strategy is applied during training to maintain policy stability. Finally, upon communication restoration, the algorithm asynchronously updates the reward function using actual historical data to correct cumulative errors introduced by the predictive model.
