+# Introduction
+
+The Energy System Simulation and Optimization System (EOS) provides a comprehensive
+solution for simulating and optimizing an energy system based on renewable energy
+sources. With a focus on photovoltaic (PV) systems, battery storage (batteries), load
+management (consumer requirements), heat pumps, electric vehicles, and consideration of
+electricity price data, this system enables forecasting and optimization of energy flow
+and costs over a specified period.
+
+After successfully installing a PV system with or without battery storage, most owners
+first priority is often to charge the electric car with surplus energy in order to use
+the electricity generated by the PV system cost-effectively for electromobility.
+
+After initial experiences, the desire to include battery storage and dynamic electricity
+prices in the solution soon arises. The market already offers various commercial and
+non-commercial solutions for this, such as the popular open source hardware and software
+solutions evcc or openWB.
+
+Some solutions take into account the current values ​​of the system such as PV power
+output, battery storage charge level or the current electricity price to decide whether
+to charge the electric car with PV surplus or from the grid (e.g. openWB), some use
+historical consumption values ​​and PV forecast data for their calculations, but leave out
+the current electricity prices and charging the battery storage from the power grid
+(Predbat). Others are specialiced on working in combination with a specific smart home
+solution (e.g. emhass). Still others focus on certain consumers, such as the electric car,
+or are currently working on integrating the forecast values ​​(evcc). And some are commercial
+devices that require an electrician to install them and expect a certain ecosystem
+(e.g. Sunny Home Manager).
+
+The Akkudoktor EOS
+
+- takes into account historical, current and forecast data such as consumption values, PV
+  forecast data, electricity price forecast, battery storage and electric car charge levels
+- the simulation also takes into account the possibility of charging the battery storage
+  from the grid at low electricity prices
+- is not limited to certain consumers, but includes electric cars, heat pumps or more
+  powerful consumers such as tumble dryers
+- is independent of a specific smart home solution and can also be integrated into
+  self-developed solutions if desired
+- is a free and independent open source software solution
+
+![Introdution](../_static/introduction/introduction.png)
+
+The challenge is to charge (electric car) or start the consumers (washing machine, dryer)
+at the right time and to do so as cost-efficiently as possible. If PV yield forecast,
+battery storage and dynamic electricity price forecasts are included in the calculation,
+the possibilities increase, but unfortunately so does the complexity.
+
+The Akkudoktor EOS addresses this challenge by simulating energy flows in the household
+based on target values, forecast data and current operating data over a 48-hour
+observation period, running through a large number of different scenarios and finally
+providing a cost-optimized plan for the current day controlling the relevant consumers.
+
+## Prerequisites
+
+- Technical requirements
+- Input data
+
+### Technical requirements
+
+- reasonably fast computer on which EOS is installed
+- controllable energy system consisting of photovoltaic system, solar battery storage,
+  energy intensive consumers that must provide the appropriate interfaces
+- integration solution for integrating the energy system and EOS
+
+### Input Data
+
+![Overview](../_static/introduction/overview.png)
+
+The EOS requires various types of data for the simulation:
+
+Forecast data
+
+- PV yield forecast
+- Expected household consumption
+- Electricity price forecast
+- Forecast temperature trend (if heatpump is used)
+
+Basic data and current operating data
+
+- Current charge level of the battery storage
+- Value of electricity in the battery storage
+- Current charge level of the electric car
+- Energy consumption and running time of dishwasher, washing machine and tumble dryer
+
+Target values
+
+- Charge level the electric car should reach in the next few hours
+- Consumers to run in the next few hours
+
+There are various service providers available for PV forecasting that calculate forecast
+data for a PV system based on the various influencing factors, such as system size,
+orientation, location, time of year and weather conditions. EOS also offers a
+[PV forecasting service](#prediction-page) which can be used. This service uses
+public data in the background.
+
+For the forecast of household consumption EOS provides a standard load curve for an
+average day based on annual household consumption that you can fetch via API. This data
+was compiled based on data from several households and provides an initial usable basis.
+Alternatively your own collected historical data could be used to reflect your personal
+consumption behaviour.
+
+## Simulation Results
+
+Based on the input data, the EOS uses a genetic algorithm to create a cost-optimized
+schedule for the coming hours from numerous simulations of the overall system.
+
+The plan created contains for each of the coming hours
+
+- Control information
+  - whether and with what power the battery storage should be charged from the grid
+  - when the battery storage should be charged via the PV system
+  - whether discharging the battery storage is permitted or not
+  - when and with what power the electric car should be charged
+  - when a household appliance should be activated
+- Energy history information
+  - Total load of the house
+  - Grid consumption
+  - Feed-in
+  - Load of the planned household appliances
+  - Charge level of the battery storage
+  - Charge level of the electric car
+  - Active losses
+- Cost information
+  - Revenue per hour (when fed into the grid)
+  - Total costs per hour (when drawn from the grid)
+  - Overall balance (revenue-costs)
+  - Cost development
+
+If required, the simulation result can also be created and downloaded in graphical
+form as a PDF from EOS.
+
+## Integration
+
+The Akkudoktor EOS can be integrated into a wide variety of systems with a variety
+of components.
+
+![Integration](../_static/introduction/integration.png)
+
+However, the components are not integrated by the EOS itself, but must be intergrated by
+the user using an integration solution and currently requires some effort and technical
+know-how.
+
+Any [integration](#integration-page) solution that can act as an intermediary between the
+components and the REST API of EOS can be used. One possible solution that enables the
+integration of components and EOS is Node-RED. Another solution could be Home Assistant
+usings its built in features.
+
+Access to the data and functions of the components can be done in a variety of ways.
+Node-RED offers a large number of types of nodes that allow access via the protocols
+commonly used in this area, such as Modbus or MQTT. Access to any existing databases,
+such as InfluxDB or PostgreSQL, is also possible via nodes provided by Node-RED.
+
+It becomes easier if a smart home solution like Homa Assistant, openHAB or ioBroker or
+solutions such as evcc or openWB are already in use. In this case, these smart home
+solutions already take over the technical integration and communication with the components
+at a technical level and Node-RED offers nodes for accessing these solutions, so that the
+corresponding sources can be easily integrated into a flow.
+
+In Home Assistant you could use an automation to prepare the input payload for EOS and
+then use the RESTful integration to call EOS. Based on this concept there is already a
+home assistand add-on created by [Duetting](#duetting-solution).
+
+The plan created by EOS must also be executed via the chosen integration solution,
+with the respective devices receiving their instructions according to the plan.
+
+## Limitations
+
+The plan calculated by EOS is cost-optimized due to the genetic algorithm used, but not
+necessarily cost-optimal, since genetic algorithms do not always find the global optimum,
+but usually find good local optima very quickly in a large solution space.
