However, the stochastic and intermittent nature of solar radiation makes prediction difficult. Inspired by this, 4 different deep learning-based hybrid models are proposed to predict short-term PV power generation using long short term memory (LSTM) neural network and convolutional neural network (CNN) based on Bayesian Optimization (BO) in this paper. In addition, this paper explores feature selection using two benchmark models on different feature sets, and finally selects 5 features for prediction. The performances of direct forecasting results for both 1-hour ahead and 24-hour ahead of the above various models are compared on one year of hourly data from a real PV plant in Shandong, China. It is shown that using Bi-directional LSTM (BiLSTM) and CNN-BiLSTM models are more suitable for 1-hour ahead prediction, LSTM-CNN and CNN-BiLSTM models are more suitable for 24-hour ahead prediction. The case study shows that the model with Bayesian optimized optimal weights can reduce the error rate by up to 32.80% compared to the benchmark model and demonstrates the good prediction performance of the proposed approach on commercial PV plants.","PeriodicalId":296085,"journal":{"name":"2021 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115283934","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}

To realize adequate reserve provision for power system, massive flexible resources in integrated electricity and heating system have been aggregated to supply efficient reserve capacity. In this context, we first propose an operating reserve quantification scheme for analyzing both probabilistic reserve requirements and dynamic reserve capability of integrated electricity and heating system; Then, a simplified model is developed through convex relaxation and polyhedral approximation for computational tractability of district heating system reserve capacity. A noval two-layer iterative algorithm based on the second order cone duality is developed to obtain a two-stage distributionally robust energy and reserve scheduling strategy. Finally, numerical simulations are implemented to validate the effectiveness and economic benefits of the proposed approach.","PeriodicalId":296085,"journal":{"name":"2021 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia)","volume":"309 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123058466","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 is urgent to find a low-carbon and environmentally friendly energy supply method suitable for rural areas. Based on low carbon environmental protection as the goal, this paper analyzed the natural resources in the rural areas and proposed a comprehensive energy system suitable to rural area, which composed of the photo voltaic, wind power, ground source heat pump, straw curing fuel for rural energy, can make full use of abundant biomass and idle land in rural area and satisfy rural residents’ demand for cold, heat, electricity. With the pollution emission factor model as the main calculation reference, this paper studies the pollution emission of energy system, and initially adopts the full life cycle method to calculate the pollution emission of photo voltaic and wind power equipment. Considering the flexible consumption of users and the initiative of operators, the capacity of energy supply equipment is selected with the goal of low carbon emission reduction and considering economic constraints. Taking full account of regional differences, the low-carbon emission reduction effects of three different energy supply modes are compared. Taking a rural area in shandong province as an example, the proportion of CO2, SO2, NOX, PM2.5 that can reduce emission is 95.41%, 97.51%, 90.31% and 97.40%, respectively. The emission reduction effect is remarkable.","PeriodicalId":296085,"journal":{"name":"2021 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116915379","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}

Based on the analysis of the relationship between the numerical weather prediction and wind power, this paper proposes a short-term wind generation combined forecast model considering meteorological similarity to improve the prediction accuracy of short-term wind power. In this method, the meteorological similarity day model, the extreme gradient boosting algorithm and the back propagation neural network algorithm are selected for achieving the short-term wind power prediction. Then, the particle swarm optimization algorithm is applied to determine the weight of each single forecasting model. Finally, the prediction results are obtained through the combination of the single model prediction results. With the realistic wind power data collected from a wind farm in Xinjiang province, the short-term wind forecasting task is achieved by the proposed method. The simulation results illustrate that the combined model proposed in this paper can effectively improve the forecasting performance of the benchmark models.","PeriodicalId":296085,"journal":{"name":"2021 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117215940","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}

From the perspective of retailers, just considering its inside customers’ characteristic is not enough, the competitiveness of DR bidding also matters, because it depends on the qualification of participating in DR market. Thus, this paper constructs a complicated DR strategic bidding model. Firstly, based on managed residential customers’ DR feature, optimize bidding considering competitors’ risk preference with deep reinforcement learning approach and guarantee the probability of winning DR bid as much as possible. Secondly, in the actual quotation process, the inaccuracy DR declaration amount or retailers’ personal bidding preference, aggressive or moderate style, leads to DR vacancy punishment or overage waste, so that produce the loss of income. Based on previous bidding model, design backup schemes for different types of retailers in advance to reduce loss. Then utilize real case to verify the effectiveness of proposed DR bidding models.","PeriodicalId":296085,"journal":{"name":"2021 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115358493","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}
