Microgrid and Blockchain: Bringing Sustainable Electricity to Myanmar Abstract Myanmar’s limited electricity infrastructure presents an opportunity to privately develop microgrids that are separate from the existing centralized grid system. The technological breakthroughs in microgrid and blockchain systems enable private investors to develop blockchain-based microgrid systems that allow prosumers- consumers who also produce energy with household solar panels- to freely trade energy within the microgrid community. A blockchain-based microgrid system that incentivizes all parties to optimally produce and consume electricity according to the aggregate supply and demand is proposed to minimize the need for storage and ensure efficient allocation of energy. Examples of the combination of blockchain and renewable energy already exist, such as SolarCoin, the first solar energy-based digital currency. A pilot project for a blockchain-based microgrid system is underway in Brooklyn Microgrid (BMG). These pilot projects are collecting data and adjusting their models to build a scalable blockchain-based microgrid model. More pilot projects are needed in Myanmar in order to identify the specific egionalr challenges and variables required for building an optimal, socially inclusive model.

This includes wide proliferation of Distributed Energy Resources (DERs), which is being driven by the following factors: ENVIRONMENT Changes in policy and regulation Globally countries have set targets for the increase of renewable As power demands continue to rise, energy and reduction of greenhouse gas emissions. For example, the UK is aiming to reduce 20% of greenhouse gas emissions by 2020. In and energy availability and reliability the US, many states have recently set renewable energy targets for become a primary concern, utilities, 2020 and beyond. commercial and industrial companies Security of supply As traditional fossil fueled generation plants are reaching end need solutions to ensure they have of life, countries need to find new sources to meet their growing a reliable, resilient, and economical demand. Implementing and managing multiple energy sources, including renewable generation, helps to maintain energy security. supply of electricity. Furthermore, local management of DERs reduces supply chain risks associated with traditional energy sources. New revenue streams Attractive feed-in tariffs for renewable generation have seen new investors outside the traditional energy industry investing in renewables bringing new entrants to the market. New commercial models are emerging including peer to peer energy transactions. Increasing availability and affordability As DERs are becoming more cost effective and readily available, there is a rise of the prosumer, where customers are both the producers and consumers of electricity. Helping enhance productivity through energy surety When industrial and manufacturing companies lose power, it can cost millions of dollars in down-time, waste and equipment damage.

Positive development has been achieved since the last decade by the collective effort of scientists. In this regard, renewable energy sources (RES) are being deployed in the power system to meet the energy demand. The microgrid concept (AC, DC) is introduced, in which distributed energy resources (DERs), the energy storage system (ESS) and loads are interconnected. DC microgrids are appreciated due to their high efficiency and reliability performance. Despite its significant growth, the DC microgrid is still relatively novel in terms of grid architecture and control systems. In this context, an energy management system (EMS) is essential for the optimal use of DERs in secure, reliable, and intelligent ways.

The storage system is one of the most crucial components since inappropriate design can affect reliability and final costs. Therefore, it is necessary to adopt reliable models able to realistically reproduce the working condition of the application. In this paper, different models of lithium-ion battery are considered in the design process of a microgrid. Two modeling approaches (analytical and electrical) are developed based on experimental measurements. The derived models have been integrated in a methodology for the robust design of off-grid electric power systems which has been implemented in a MATLAB-based computational tool named Poli.NRG (POLItecnico di Milano—Network Robust desiGn). The procedure has been applied to a real-life case study to compare the different battery energy storage system models and to show how they impact on the microgrid design.

  • COMBINING MULTIPLE POWER SOURCES for MAXIMUM EFFICIENCY and UPTIME the Energy Industry Is Changing
    Power generation AN INTRODUCTION TO MICROGRIDS; COMBINING MULTIPLE POWER SOURCES FOR MAXIMUM EFFICIENCY AND UPTIME The energy industry is changing. Demand for decentralized energy sources that don’t rely on the traditional power grid, from solar cells to combined heat and power plants, continues to grow. At the same time, advancements in digitalization have already transformed many industries. The combination of these two forces has led to the emergence of small-scale power networks called microgrids. Through the integration of multiple power sources, microgrids can maximize efficiency and ensure uninterrupted power. By Brian Ponstein What is a microgrid? Senior Application Engineer A microgrid is a flexible and localized power generation system that combines multiple And Christian Mueller assets. While each system is unique, they all share common elements. A microgrid Senior Sales Engineer utilizes renewable energy sources such as solar panels, wind turbines, battery storage, Gas Power Systems diesel gensets and combined heat and power (CHP) modules–operating separately or in parallel. Diesel or gas generator sets may also be included, along with battery banks to store electricity and deliver it when needed. Control systems are a critical component to every microgrid, designed to provide exactly the right energy mix for the customer. Since a microgrid is used primarily for local demand, typical users are local energy consumers (industry, residential, service providers, municipal services). These users may be on the grid with unlimited access or off the grid, running self-sufficient island operations.
