Local Electricity Markets introduces the fundamental characteristics, needs, and resource constraints shaping the design and implementation of local electricity markets, and addresses proposed local market models and lessons from their limited implementation. The book discusses decision and informatics tools considered important in the implementation of local electricity markets. It features a review of management and trading platforms, including commercially available tools. Aspects of local electricity market infrastructure are identified and discussed, including physical and software infrastructure, regulatory frameworks available for local electricity market development internationally, and barriers and opportunities for local electricity markets in the future. Delineates key components shaping the design and implementation of local energy market structure Provides a coherent view on the enabling infrastructures and technologies that underpin local market expansion Explores the current regulatory environment for local electricity markets drawn from a global panel of contributors Exposes future paths toward widespread implementation of local electricity markets using an empirical review of barriers and opportunities Reviews relevant local electricity market case studies, pilots, and demonstrators already deployed and under implementation

This thesis presents a system analysis for co-operation in local electricity markets including distributors and customers. The purpose of co-operation is to minimise the system cost of local markets by introducing system measures, such as end-use measures and municipal co-generation plants. Co-operation will strengthen the position of local markets in the national as well as future international electricity markets. With end-use measures local markets will achieve flexibility, additional reserve capacity and ability to avoid sudden large costs for peak loads. Biomass-fired cogeneration plants can become of great importance in an international market. In Sweden there is a simultaneous demand for electricity and district heating, many local markets already include district heating systems and there are major forest areas which can contribute with renewable fuel. The system analysis is partly based on the simulation model (INDSIM) and the linear programming model (MODEST). The simulation model has been further developed (STRATO) to include calculation of system costs. Shadow price analysis has been developed in order to study incentives for system measures. Calculation procedures have been developed that describe cooperation between distributor and customer. Six case studies of a selection of real, existing local markets in Sweden are presented. The studies show the potential economical effects of co-operation measured by system costs and shadow prices. Co-operation has been considered between demand- and supply-side, electricity- and district heating systems and also between different time periods. In a typical local market with 90 000 inhabitants, if end use measures are introduced without cooperation the system cost of the distributor will increase by 14 million SEK for a time period of 25 years. If instead end-use measures are introduced in co-operation, together with a biomass-fired cogeneration plant, the system cost of the local market will be reduced by 444 million SEK. Furthermore, the use of biomass in the local market is increased from 36 to 72 % while the use of oil is decreased from 34 to 1%. Another case study of another local market (50 000 inhabitants) shows that end-use measures will reduce the system cost (excluding investment costs) of an industry by 50 % corresponding to 1.3 million SEK for one year. The end-use measures imply reduced power demand during peak load periods in the local market and increased power demand during non- peak load periods.

This master thesis has as an objective the development of an electricity market. It is a research project that aims to be the foundation for a bigger and more thorough analysis. It examines the implementation of a local electricity market in a residential network equipped with renewable generation and storage technologies. In the context of this project the electricity market is defined as a real-time market focused on the exchange of active power. This thesis focuses on examining the effects on electricity prices that different pricing and consumption strategies have. In this context the feasibility of the results, from a power flow point, are not examined. The network in question is considered to be connected to the low voltage, alternating current grid and it comprises exclusively of households. It is a perfectly competitive market in the sense that no single player can exercise market power on his own, in order to raise prices. Simulations are conducted in a MATLAB environment to investigate the effects of different pricing and consumption strategies on the clearing prices of the market, as well as to determine the viability of such a market. The viability of the project in the context of this thesis is examined only from a financial aspect. Prices are not chosen arbitrarily but aim to mirror real world costs and more specifically the Levelized Costs of Energy and Storage. It is against these quantities that the resulting prices are compared to conclude about the viability of the project. Furthermore a cartel situation is simulated to investigate possible outcomes. Again in the context of this thesis a cartel is assumed to be a consortium of players colluding for financial gain, a fraction of the market players that offers higher prices and instigate atypical market operation. The results demonstrate the viability of such a market, as well as the effects of the cartel situation. Each scenario is examined separately and then compared against the rest. Finally a cost analysis is conducted in order to show the costs of such a study in the real world.

In the context of distributed generation growth, local grids could face operational issues. In that sense, smart grid deployment will give information to local grid operators about grid status at medium and low voltage levels for taking operational decisions on daily basis. This thesis presents local markets as a potential solution to avoid local grid congestions and over-costs. They mainly increase the negotiation power of end-users with distributed energy resources and allow activation of flexibility at local level.First of all, this thesis analyses electric vehicles as a potential challenge for distribution grids and electricity markets in case of uncontrolled charging as it could cause consumption peaks. At the same time, electric vehicles could be part of the solution thanks to their capability of shifting forward their consumption. The first solution presented in this thesis is a building level electric vehicle management algorithm in order to reduce energy cost and consumption peaks.However, local grid operators need a solution to deal with aggregated level problems like high demand or high generation periods. Such kind of problems vary over time and place, and they could be difficult to integrate in regular grid tariffs. Therefore, the present thesis provides two local market designs for these problems. The first local market presented is designed for taking advantage of renewable energy producers before and after the whole-sale day-ahead market without threatening distribution grids and increasing the local social welfare. However, this market implies significant regulatory changes because the local market operator should take sorne of the current local grid operator regulated activities.Therefore, this thesis presents a second market design for managing portfolios of consumers, producers and prosumers, and it could be operated by retailers, balance responsible parties or aggregators for flexibility provision without regulatory issues. The work includes a description of roles, contracts and interactions of such local flexibility market, and three optimization algorithms depending on the application, complexity and portfolio scale. The first algorithm assumes limited information about each site, the second one includes such information but presents potential scalability limitations, and the last algorithm is based on a decomposition method to optimise the aggregator portfolio in a distributed way reducing the computational burden and time.

Regulation & Investments in Energy Markets: Solutions for the Mediterranean presents the status of advancement and maturity of the Mediterranean energy policy, identifying patterns of development as well as lessons learned. Mediterranean countries are facing unprecedented challenges in the energy sector which affect the entire region. Energy policy and regulation is the key to tackling energy efficiency challenges, and providing favorable conditions for engineering infrastructures, investments, and improving security of energy supply. The assumption that the normative model, on which the EC energy policy is based, could be adopted outside EU boundaries has proven to be difficult to implement. This book looks at the Mediterranean regions search for a revised model for regulatory convergence and provides answers to those research questions, allowing the reader to understand the different technical, institutional, and financial frameworks for energy policy. Contains a detailed overview of the specificities and institutional frameworks, giving greater clarity on existing energy practice Provides recommendations and contributions from leading scholars and key players in energy policy research Presents information from a region wide interdisciplinary approach based on specific industry information
