After the heating transformation of pure condensing thermal power unit, its regulating capacity has changed significantly. Therefore, the technical research of test and theoretical modeling is carried out. The minimum power value of the generator under steam extraction condition is tested through the test, and then the maximum output power value of the generator is obtained by considering the power loss caused by steam extraction. In this way, the steam extraction flow electric power model is obtained to calculate the regulating capacity in real time. According to the online visible regulation capacity, this can guide the stable operation of the power grid.

The results of existing energy storage planning of the Distribution Network (DN) are energy storage configurations with fixed access points and capacity. There is still a lot of room for the flexibility and value of energy. With many renewable energies distributed generation (DG) connected to the distribution network, it can be divided into different operating scenarios according to the seasonality of distributed power and loads in the distribution network. This paper proposes a Mobile Energy Storage (MES) configuration planning method of the DN. Through this method, the MES devices are dynamically allocated between different operating scenarios of the DN regarding the varying load demands as well as DG outputs. The access points, capacities and operation modes of MES devices in various scenarios are taken as the decision variables, the maximum comprehensive economic benefit brought by MES is taken as the objective, and thus the mixed-integer second-order cone programming(MISOCP) model for MES configuration is constructed. Case studies are performed in the modified IEEE 33-node distribution systems. The feasibility and effectiveness of the proposed method are verified The proposed method can be treated as a useful expansion to the flexible operation of energy storage device, through which the MES can well service for various operating scenarios of the DN and thus its value can be fully developed.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122598185","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 proposed paper proposes a data-driven method to generate the stability boundary, by quickly sampling as many as possible the OPs which the damping ratio of its are close to the stability boundary with critical N-1 contingencies. To achieve this goal, a sample method with the self-adapting step size based on the damping ration sensitivity and critical contingencies selection based on the network theory are proposed in this paper.

The distribution system operator (DSO) and each microgrid (MG) are considered as different entities with various objectives. In each MG, the Wasserstein distance based ambiguity set is utilized to describe the uncertain distribution of renewable generation. Due to the coupling power exchange, the alternating direction method of multipliers (ADMM) is applied to solve the problem in a decentralized manner.

The growing proportion of wind generation in power grid gives rise to frequency instability problem. The increasing load demand in power grid worsens the load peak-to-valley difference problem. Battery Energy Storage System (BESS) has the capability of frequency regulation and peak load shaving, but its high economic costs need to be taken into consideration. To address this issue, this paper proposes a sizing strategy for BESS with wind integration under the condition of frequency regulation and peak load shaving. In the case of eliminating frequency deviations, the sizing of BESS is decided by the approximated Laplace distribution based on wind power prediction errors. As for peak load shaving, the load interval control method is used for the sizing of BESS.

To release the electricity supply pressure, time of use price is implemented in some cities to transfer the charging demand of household EVs from peak period to valley period. However, plenty of EVs choose to charge intensively at the beginning of valley period, which causes a new load peak and wastes the potential of peak shaving and valley filling. To address the problem, this paper proposed the optimal charging scheduling strategy for household EVs under time of use price. Firstly, the charging model and process of the EV are developed to describe the various charging demands accurately. Subsequently, EVs with optimization potential are screened to improve the efficiency of time scheduling. In order to shorten the peak-valley difference of the residential load, the charging periods of EVs are optimized utilizing the genetic algorithm. Finally, based on the actual data of residential load and EVs, the time scheduling simulation is studied to show the optimization performance. By making full use of the peak-shaving and valley-filling capacity of EVs, the simulation results proved the effectiveness of the proposed method on charging time scheduling, the peak load caused by centralized charging demands decreased. Besides, the residential power during the peak period is effectively reduced and the power during the valley period is improved.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131836792","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}
