Firstly BSC (Balanced Scorecard) based KPIs are created so as to provide fully vision on distribution network situation evaluation. Then AHP method is used to determine the index weight and situation evaluation is performed. Based on the evaluation method and result, Gray theory method is applied for situation prediction of distribution network.

The integrated energy system is a new form of energy utilization that organically combines multiple energy resources such as cold, heat and electric power. It has the advantages of high comprehensive efficiency, better economic benefits, and less pollution emissions. In this paper, a medium and long-term load forecasting method for integrated energy systems based on source-load evolutionary game is presented. With the help of Stackelberg game and alternate iteration strategy, this method can model the multi-energy coupling relationship and the evolution behavior of source-load, so as to realize the accurate prediction of various loads.

Aiming at conducting comprehensive optimization for the integrated system which consists of electric power loads, heating and cooling loads, this paper established an optimization model with the objective of the lowest power supply costs, while considering the priority of renewable energy consumption and the role of time-of use electricity prices of power grid, and taking into account different operational constraints, such as supply and demand balance of electricity, heating and cooling, CCHP outputs, etc.. An example system was selected to study the operational economics of the integrated energy system having interaction with the power grid or with the battery storage system. Study results show that battery storage system is more effective in reducing operational cost than interactive operation of the power grid because of the mismatch of PV generation and peak load need.","PeriodicalId":321188,"journal":{"name":"2020 4th International Conference on Power and Energy Engineering (ICPEE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131986943","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}

In the existing researches on energy flow calculation, only the friction head loss is considered and the influence of local head loss is not involved because of the complexity of the pipe structure. The local head loss occurring at abrupt flow boundary changes, such as variable section pipes, pipe inlet and outlet, and pipe connections is inevitable. The output of units and energy flow distribution in the IES will be affected by energy consumption caused by local head loss, so it is necessary to calculate the energy flow with local head loss in mind. In this paper, a local head loss energy model at pipe connection is first established, then a solution model for the energy flow of the electricity-heat IES with local head loss model is established, and the model can be solved by N-R method. Finally, the effectiveness of the model and the influence of local head loss on the whole system are verified through case comparison. The result shows that energy loss caused by local head loss should be avoided although it's a small amount of energy for the whole system.","PeriodicalId":321188,"journal":{"name":"2020 4th International Conference on Power and Energy Engineering (ICPEE)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121151728","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}
