Description

preamble

The present invention relates to a smart home for a power supply network of energy consumers and energy consumers of an energy supplier according to the preamble of claim 1.

State of the art

Systems for regulating the individual energy balance in the individual house (smart home) are known, for example. From US 2010 211 224. This internal data (temperature, etc.) and external data (weather information, etc.) in one Controller processed in such a way that the internal heating, cooling and fan systems are operated cost and CO2-poor. In addition, energy management systems for smart homes are also known, for example from US 2014 0 052 303, in which a central controller is networked with in-house energy consumers, energy generators and energy stores, to the user via an interface and a data transmission system display in-house energy profile and make recommendations for in-house / on-site energy conservation and / or on-site / on-site power generation and / or on-site energy storage. The content and teaching of this document are intended to be the entire contents of this application.

disadvantage

The generated consumer profile and the retrievable information are merely consumer-oriented and serve to control consumption, i. E. merely show the consumer where and how a cost saving or reimbursement benefit could be achieved. However, an optimization of the energy industry taking into account all in-house systems is not possible. In addition, none of the known systems takes into account the stability of the in-house and / or external energy network with strong power fluctuations of the in-house energy consumers, energy storage and / or energy producers, eg. In case of failure or overproduction of the in-house power generator.

problem

Object of the present invention is therefore to provide a power supply system, which ensures the stability of the in-house and external energy network in case of failure, under-production or overproduction. In addition, the self-sufficiency of the individual consumer and his total energy costs are to be optimized with this energy supply system.

solution

This object is achieved according to the invention with a smart home according to claim 1 and in particular with a smart home for an energy supply network of energy consumers and Energieprosumenten an energy supplier, which composite at least a common power grid, a common gas network and a common information network ( for real-time data transmission), this energy supply network comprising a hybrid plant and this smart home an in-house complementarity to optimize the efficiencies / annual use figures / annual work and / or a system complementarity to minimize energy costs and optimization of Autarkiegrades and / or a Energy complementarity for optimizing the grid relief and the balancing energy with the energy supplier, and in this smart home an in-house energy management system (with means for recording, calculation and visualization of the current and / or annual n Autarkiegrades) is provided, and which in-house energy management system is coupled via the common information network (with real-time transmission) with an external control system of the hybrid plant.

definitions

In the following means autarky that the entire energy consumed in the smart home (electricity, gas, heat, etc.) is generated or produced by own means and independently. Self-sufficient systems supply themselves exclusively with their own energy and are independent of imports. The level of self-sufficiency is defined by the ratio of own production to total consumption. Consumers are intended to refer to energy consumers who receive electricity and / or gas, i. have their own oil heating, a heat pump and / or gas heating, etc.

Prosumers are to be understood here energy consumers who have in-house energy-generating plants, in particular those for electricity (PV system, wind power, etc.) and / or for gas production (via electrolysis, methanation, pressure vessel, for fuel cell, vehicle , etc.) and provide shares of self-generated energy in a power or gas network. <Tb> in-house Komplemetarität: <September> prosumers-sufficiency <tb> System complementarity: <SEP> intelligent mix of home installations allows simultaneous energy exchange between prosumers / consumers <tb> Network Complementarity: <SEP> simultaneous balancing of energy supply and energy demand in the electricity grid <tb> Energy complementarity: <SEP> delayed balancing among different energy sources in the network of the energy supplier.

advantages

For the pure consumer: required loads can be switched on at the same time by the energy supplier, if the supply of prosumers is higher than the demand. For the prosumers with network storage: Surplus electricity can be stored in the network and can be re-allocated to electricity and / or gas with a time delay. Increase the self-consumption quota, i. Promotion of self-sufficiency in the smart home. tariff optimization consumption visualization Stable supply network Cost optimization, i. Over-production of electricity from the summer can be used in winter, for example in the form of gas

embodiment

In the following, the invention will be explained in more detail with reference to embodiments and with the aid of the figures. Showing: <Tb> FIG. 1 is a schematic representation of the inventive energy complementarity of a regional energy interconnected system with several local smart home interconnected systems; <Tb> FIG. 2 <SEP> is a schematic representation of the inventive in-house and system complementarity in a plurality of smart home configurations in a local smart home network system.

figure description

Fig. 1 illustrates the principle of dynamic networking, which allows the individual consumers / prosumers and / or the local composite systems market-oriented autarky growth. Each individual smart home has an in-house, system and energy complementarity. The local interconnected systems are coupled together via a common energy grid (electricity, gas, district heating) and a real-time data transmission line and connected to a hybrid plant. The moderation (network control) of the individual smart home and local interconnected systems is managed via a regional energy data management system.

The smart home network system shown by way of example in FIG. 2 shows a plurality of possible in-house energy generation plants and energy loads, typically: House introduction with central network and system protection, including energy metering (gas, electricity meter) and firewall; Photovoltaics with energy metering and feed-in management; Solar collector; Wind power; WP (heat pump); Electricity storage with energy metering and system switch; WKK (heat and power cogeneration, heat generation, gas heating) with energy measurement and system switch; Heat storage (with BWW) with energy metering and plant circuit; Automation system with interfaces for communication; Comfort devices (air conditioners, sun blinds, washing machines, etc.) Visualization of the connection and the degree of self-sufficiency Control of energy optimization (energy manager).

Energy manager includes the determination of the final energy, useful energy, storage potential, self-generated energy, return delivery, self-consumption (Autarkiegrad) and optimizes the utilization of the in-house facilities such that the current, resp. Annual utilization rates of all installed systems (in-house complementarity) to a self-sufficiency optimization and thus to an energy cost minimization. The current, resp. Annual self-sufficiency in% is determined by self-consumption / total consumption, especially including gas. In principle, the on-site generated energy (electricity, gas, etc.) should be used primarily for own use, since usually the savings from electricity not sourced from the supply network exceeds the remuneration for the feed-in.

The coupling of the in-house energy manager with the power data manager of the control system allows moderation of the network load by optimizing the interaction between the consumer / prosumer and the energy supplier. In particular, this networking allows a timely provision of required balancing energy through the intelligent use of a hybrid plant.

For example, the loads of the individual smart home's can be switched on at the same time by the energy suppliers, if the energy supply of the prosumers is higher than the demand. For all prosumers, the power surplus is stored in the network and can be related in time to electricity or gas.
