-- OS: Linux, Windows, macOS
-
-Note: For Python 3.13 some dependencies (e.g. [Pendulum](https://github.com/python-pendulum/Pendulum)) are not yet available on https://pypi.org and have to be manually compiled (a recent [Rust](https://www.rust-lang.org/tools/install) installation is required).

-# 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.
