| Hybrid power plant + | A hybrid power plant can combine multiple conversion plants in itself to increase their efficiency and to make them more flexible. Because of this, fluctuations of energy scources can be balanced and the energy needs-based generated., A hybrid power plant describes a power plant where different energy transformation processes and energy generation processes are linked with eachother. A hybridpower plant is used for electricity generation, fuel production and heat generation of different primary energy sources. In the process multiple conversion plants get connected with storages and energy consumers. Renewable energy plants and energy plants based on fossil fuels belong to conversion plants. The energy consumers are heating network, petrol stations, gas networks and supply networks. |

| INSPIRE + | 1. INSPIRE is "an EU initiative to establish an infrastructure for spatial information in Europe that is geared to help to make spatial or geographical information more accessible and interoperable for a wide range of purposes supporting sustainable development"., The INSPIRE directive lays down a general framework for a Spatial Data Infrastructure (SDI) for the purposes of European Community environmental policies and policies or activities which may affect the environment. The INSPIRE Directive entered into force on 15 May 2007. |
| Incoming Flow + | Mass or energy flow entering a system or component. |
| Inner Join + | 1. An inner join requires each row in the two joined tables to have matching column values, and is a commonly used join operation in applications but should not be assumed to be the best choice in all situations. Inner join creates a new result table by combining column values of two tables (A and B) based upon the join-predicate. The query compares each row of A with each row of B to find all pairs of rows which satisfy the join-predicate. When the join-predicate is satisfied by matching non-NULL values, column values for each matched pair of rows of A and B are combined into a result row., 2. The Inner Join keyword selects records that have matching values in both tables. |
| Input (Computer) + | Whenever you enter data into your computer, it is referred to as input. This can be text typed in a word processing document, keywords entered in a search engine's search box, or data entered into a spreadsheet. Input can be something as simple as moving the mouse or clicking the mouse button or it can be as complex as scanning a document or downloading photos from a digital camera., The opposite of input is output. |
| Input parameter + | Parameter which affects the system and which has to be given for each calculation (external , fixed or adjustable system parameter). |
| Integer + | 1. In computer science, an integer is a datum of integral data type, a data type that represents some finite subset of the mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits). The size of the grouping varies so the set of integer sizes available varies between different types of computers. Computer hardware, including virtual machines, nearly always provide a way to represent a processor register or memory address as an integer., 2. An integer (from the Latin integer meaning "whole") is a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75 and √2 are not. The set of integers consists of zero (0), the positive natural numbers (1, 2, 3, …), also called whole numbers or counting numbers, and their additive inverses (the negative integers, i.e., −1, −2, −3, …). This is often denoted by a boldface Z. |
| Interconnection + | 1. There are basically two possibilities for connecting solar cells and PV modules:, The parallel circuit and the series circuit, The type of interconnection influences how the central electrical variables of the individual components (the current voltage, the current intensity and the power) change in the newly formed component., 2. A single cell can be connected to multiple cells in one module. It is also possible to connect several modules together., This electronic connection is called interconnection. |
| International Morse Code + | 1. Morse Code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment., 2. Morse code is a method of sending text messages by keying in a series of electronic pulses, usually represented as a short pulse (called a "dot") and a long pulse (a "dash"). |
| Interpretation + | 1. "Interpretation is the act of explaining, reframing, or otherwise showing your own understanding of something.", 2. " An explanation or conceptualization by a critic of a work of literature, painting, music, or other art form; an exegesis." |
| Irradiance + | 1. Irradiance is the radiant flux (power) received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W/m2)., 2. The direct, diffuse, and reflected solar radiation that strikes a surface. Usually expressed in kilowatts per square meter. Irradiance multiplied by time equals insolation. |

| Join + | 1. A SQL join clause combines columns from one or more tables in a relational database. It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one (self-table) or more tables by using values common to each., 2. A JOIN clause is used to combine rows from two or more tables, based on a related column between them. |

| LV grid district + | 1. An area that is connected to one LV substation. |
| Learning simulation + | 1. A learning simulation is an experience designed to rigorously help users develop competence and conviction. A learning simulation is a combination of modeling elements, entertainment (or game) elements, and instructional (or pedagogical) elements. These can range from pure media (which do not involve any other humans), to experiences that use coaches, teammates, competitors, and communities. |
| Levelized Costs of Electricity + | 1. The levelized cost of electricity (LCOE) is a measure of a power source which attempts to compare different methods of electricity generation on a consistent basis. It is an economic assessment of the average total cost to build and operate a power-generating asset over its lifetime divided by the total energy output of the asset over that lifetime., 2. The concept of levelized cost of electricity is used to compare the cost of energy coming from different sources., LCOE = Total cost of ownership ($) / System production over its lifetime (kWh) |
| Library + | A library is a collection of sources of information and similar resources, made accessible to a defined community for reference or borrowing. It provides physical or digital access to material, and may be a physical building or room, or a virtual space, or both |
| Licence + | 1. Revocable written (formal) or implied agreement by an authority or proprietor (the licensor) not to assert his or her right (for a specific period and under specified conditions) to prevent another party (the licensor) from engaging in certain activity that is normally forbidden (such as selling liquor or making copies of a copyrighted work). Intellectual property licenses generally mean that the licensor will not invoke ownership protection laws if the licensed property (art, design, patent, etc.) is copied, sold, or used by the licensee. A license is not a right, because the licensor may not have the legal power to give all necessary permissions that constitute a legal right., 2. A special permission to do something on, or with, somebody else’s property which, were it not for the license, could be legally prevented or give rise to legal action in tort or trespass. |
| Light Induced Degradation + | 1. LID (Light Induced Degradation) is a loss of performances arising in the very first hours of exposition to the sun, with Crystalline modules. It may namely affect the real performance with respect to the final factory flash tests data delivered by some PV module providers. It is unclear how it affects the performances with respect to the specified STC values. If the modules are sorted according to their final factory flash test for determining their Nominal Power class, the LID will indeed represent a loss with respect to STC. The LID loss is related to the quality of the wafer manufacturing, and may be of the order of 1% to 3% (or even more). It is due to traces of Oxygen included in the molten Silicon during the Czochralski process. Under the light exposition effect, these positive-charged O2 dimers may diffuse across the silicon lattice, and create complexes with boron dopant acceptors. The boron-oxygen complexes create their own energy levels in the silicon lattice, and can capture electrons and holes which are lost for the PV effect., 2. Crystalline p-type boron doped silicon solar cells generally exhibit a degradation of conversion efficiency during the first hours of exposure to the sun light. This light induced degradation (LID) is associated with the formation of the well known boron oxygen complex which acts as a harmful defect and reduces the minority carrier diffusion length accordingly. LID is therefore related to both, boron and oxygen concentration. |

| Lithium-ion battery + | A few examples for different lithium-ion batteries are: lithium titanate batteries (LTO), lithium- cobaltdioxid batteries (LCO), lithium-manganese batteries(LMO, LNMO), lithium-polymer batteries, lithium-iron phosphate batteries (LFP), lithium-air batteries or tin-sulphur-lithium-ion batteries., The positive electrode of a lithium-ion battery usallay consists of lithium alloys or lithium-metal oxides. The negative electrode consists of graphite, silicon or lithium-titanates., Li-ion batteries are mainly used for portable divices with a high demand for energy like laptops, cameras, mobile phones etc. They are also used in the field of electromobility for pedelecs, e-cars or hybrid cars., Lithium-ion battery is a superterm for a huge nummber of battery versions. Electrodes and electrolytes require a lot of different materials in a variety of combinations. Through these new cell types have emerged and are emerging which makes a summary about the different lithium-ion batteries impossible., Electrolytes are liquid and often organic. They can also exist in a (nearly) solid state through gelation. Since lithium is rather reactive with water aqueous electrolytes cannot be used. |
