Power quality is a major issue with microgrids because they tend to have low short circuit power with higher levels of harmonic distortion and asymmetry than major power grids. Energy delivered to the customer by distorted and asymmetrical voltages and currents can be composed of a useful component and a component that can be harmful to customers and/or the utility. Unfortunately, traditional analog based energy meters are incapable of distinguishing these components and billing for them appropriately. Using a new concept of working, detrimental, and reflected active power, via the advanced metering infrastructure, sources of degradation can be pinpointed so entities responsible for harmonic distortion and asymmetry can be made aware of the issue. A model of a microgrid bus will demonstrate the con- sequences of distortion and asymmetry. Enforcing penalties can result in better voltage and current profiles thus increasing the overall efficiency of the microgrid for a minimal cost of software updates to AMI meters.","PeriodicalId":372982,"journal":{"name":"2014 IEEE Green Energy and Systems Conference (IGESC)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130575098","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}

One major benefit is data and communications that enable customer-side resources to participate in electricity programs - i.e., transact with the electric grid. The U.S. Smart Grid activities and investments, which account for nearly three billion dollars in publicly documented expenses, build on interoperability standards activity. Standards interoperability for grid transactions can be viewed from two key interfaces - between (1) Smart Grid domain interfaces, and (2) customer-side resources and the electric grid. Conformance testing and certification is key to ensuring that standards are interoperable and secure. This paper describes the conformance development and certification process for a key communications standard - Open Automated Demand Response (OpenADR) - as an interface between customers' systems and electricity service providers, to enable demand response and price transactions. Through this process, we describe the benefits of conformance to support low-cost automated DR (AutoDR) and customer-side transactions within the distribution electric grid. The paper evaluates examples of applications and further developments for emerging transactive energy concepts that can be used to scale existing systems and to leverage the investments and support compliance to any building codes and appliance standards. The conformance process can be the key to realizing interoperability benefits and market acceptance. Conformance is also a key to enabling native DR and price transaction capabilities in customers' systems; a feature that can be replicated for diffusion and can lower DR technology costs by a significant margin.","PeriodicalId":372982,"journal":{"name":"2014 IEEE Green Energy and Systems Conference (IGESC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128454620","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 CHP plants, generation of heat and power follows a joint characteristic, which means that production planning of both commodities must be done in coordination. The hourly produced power can be sold to the grid at market price, but heat must be produced to meet the local demand of district heating or heat for specific industrial processes. Typically, the most profitable operation of a CHP system can be planned by using an optimization model. The high efficiency and profitability of CHP plants can be further improved by utilization of energy storage units. Heat storages make it possible to relax the constraint to produce heat each hour to exactly match the local demand. This allows satisfying the variable heat demand more cheaply by storing heat during low demand and discharging heat when demand is high. By relaxing the connection between heat and power production, heat storages also allow producing more electricity to the power market when the spot price is high and reducing the power generation when spot price is low. The aim of this study is to develop a model for optimizing the operation of a CHP plant together with a heat storage. The model is a linear programming (LP) model consisting of hourly models connected together with dynamic storage constraints. The objective is to minimize the production (fuel) costs subtracted by revenue from selling power to the market. The model is demonstrated using modified reallife data of a Finnish city. The results are useful for planning efficient operation of the plant. The model can also be adapted for determining the optimal size of the storage.","PeriodicalId":372982,"journal":{"name":"2014 IEEE Green Energy and Systems Conference (IGESC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131628508","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}
