The purpose of this paper is to present a new approach to formulate the problem as a single-objective optimization problem incorporating a practical emission trading mechanism by considering cap-and-trade scheme which is successfully used in USA. The economic and emission dispatch problem is solved by a two-stage optimization process to cope with the cap-and-trade program. In the first-stage, required emission allowances to supply a particular demand is estimated by a pre-dispatching process that takes into account unit commitment and set bid price (BP) of the primary emission market auction. In the second-stage, final dispatch is calculated using unit commitment, primary emission market bid settlement price (BSP), and secondary market price (SMP) of emission allowances. The performance of the proposed dispatching process is validated by a case study on a modified IEEE 30 bus system which includes three cases indicating that the proposed method (PM) provides the optimal combined solution of economic and emission dispatch for electric utilities.","PeriodicalId":231713,"journal":{"name":"2016 IEEE Green Energy and Systems Conference (IGSEC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125286407","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}

As the national leader in the development of offshore wind farms and nuclear power plants, East China Grid is also the primary receiving end of national ultra-high voltage backbone power grids. However, intermittent outputs by renewable sources and inflexible ultra-high voltage direct current together threaten the viability of maintaining reliable and high-quality electric service for consumers. This paper proposed practical ways for East China Grid Corporation to absorb renewables as much as possible under its high proportion of coal-fired power plants. It shows that pumped hydropower plants still have potential to help more about peak-regulation but require market incentives. And the nuclear power plants in East China Grid which equal half of nationwide nuclear capacity, will contribute significantly via load-following operation.","PeriodicalId":231713,"journal":{"name":"2016 IEEE Green Energy and Systems Conference (IGSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122679401","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}

CSP offers a number of advantages over photovoltaic at large scale power generation, such as lower cost and the option of thermal energy storage. However, the costs of a power tower plant are dominated by heliostats, which are usually 50% of the entire facility. NASA5s Jet Propulsion Laboratory was awarded funding by the DOE SunShot Initiative to develop a low-cost, rigid foam-based solar concentrator to meet installed cost goals of S75/m2 vs. current costs of - $200-250/m2. The design approach was validated by building and testing of a small-scale (6m2) heliostat prototype. Based on the findings of this prototype costs estimates for high production volume using industrial manufacturing technologies were conducted. The findings of these studies as well as lessons learned from manufacturing of the prototype are presented in this paper.","PeriodicalId":231713,"journal":{"name":"2016 IEEE Green Energy and Systems Conference (IGSEC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131174031","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}

Building efficiency is the largest growing segment in the US, the estimated global revenue by the building efficiency sector is around 210 million dollars, and constantly increases since 2011. Much research already shows the players' passive and conservative attitudes to enter into the energy efficiency market. Especially there are obstacles for the construction companies to redesign their business model from the traditional building business to the smart building market. This paper conducts a qualitative approach with primary and secondary data to investigate the Barriers and opportunities of the construction companies into the smart building market. The result shows the willingness of the players to involve the building efficiency business with huge potential monetary benefits.

Transmission line is employed to transfer energy to a city. Transmission line is a complex system, so the transmission line's overload is always a challenging problem for utilities protection engineers. As a result, a series compensating capacitor (SCC) is placed along the transmission line to make the power factor correction, and increase the load capability. However, adding the SCC to the transmission line increases the potential risk of subsynchronous resonance (SSR) at a low frequency oscillation, which may lead to a possible torsional interaction and damages the turbine generator shaft when the mechanical frequency falls below the electrical frequency of the grid. To studies the SSR phenomenon, the mathematical model of the IEEE second benchmark (SBM) is utilized and computed at the system operating point, and then compensated with an analog proportional integral and derivative (PID) controller to the linearized and controllable transformed model of the system. The extended discrete PID controller is developed from an analog PID controller via bilinear transformation, which yields similar result. This extended discrete PID controller is a preferred method in preventing the SSR in the power system for its flexibility updating parameters of the nonlinear system to tolerate variation in different operational conditions.","PeriodicalId":231713,"journal":{"name":"2016 IEEE Green Energy and Systems Conference (IGSEC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128576401","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}

Recent practice has introduced renewable energy to decarbonize the data-center operation. This paper studies how to leverage the demand response of a group of distributed data centers to exploit the diversity of renewable generations and energy prices in a smart grid. We model the data-center operation as an energy cost minimization problem, in which a data-center operator jointly optimizes the energy supply and computing workload allocation for distributed data centers. To solve this problem, we design a distributed demand response algorithm that involves little information exchange yet effective interactions between the operator and data centers. Specifically, the operator updates the dual variable and broadcasts to the data centers, and each data center optimizes its operation separately as a response to the dual variable. Using data-center workload traces and renewable energy data, we validate our solution method and the simulation results show the optimal computing workload allocation and energy management across distributed data centers.","PeriodicalId":231713,"journal":{"name":"2016 IEEE Green Energy and Systems Conference (IGSEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131636551","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}
