A STYLIZED ECONOMIC MODEL ON PV PROSUMERS ENCOMPASSING GENERATION AND STORAGE ECONOMIC REQUIREMENTS, LOAD MANAGEMENT, GRID EXCHANGES AND REGULATION RULES

摘要

Driven by technical advances and favorable regulatory measures (albeit only in a fewcountries), the deployment of electricity generation at very small scales, or microgeneration,is shaping a new segment of the electricity system. On-side microgenerationprovides electricity services to homes and commercial and industrial businesses fromtheir own premises. Microgeneration can use very different techniques and fuels. Ourcontribution focuses on photovoltaic (PV) demand-side generation in residential houses,shops, warehouses or industrial buildings. As it is known, these PV plants currentlyhave up to 25 kW. However, there might also be plants with capacities up to 500kW,e.g., shopping malls or industrial warehouses. All these cases can be considered micro-Photovoltaic Generation (mPVG) if the generated electricity is not to be sold only in themarket. The mPVG plants increasingly include batteries and, in a not distant future,devices for load management. Load management embraces energy savings and energyefficiency goals which could be achieved through measures such as the installation ofappropriate appliances, the improvement of the building insulation, the optimization oflighting points, and so on. As a result, the mPVG plants will become a non-negligibletechno-economic complex. The three pillars of mPVG (generation and storage, loadmanagement, and grid exchanges) will be on the one hand influenced by specificregulations and, on the other hand, by factors such as income, household compositionand lifestyle. Our contribution proposes a stylized model to highlight the maineconomic and regulatory factors shaping mPVG.
