Description

Preamble:

The present invention relates to a smart home for an energy 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-2010211224. Internal data (temperature, etc.) and external data (weather information, etc.) are processed in a controller in such a way that the internal heating, cooling and fan systems are operated with low costs and low CO2 emissions. In addition, energy management systems for smart homes are also known, for example from US-20140052303, in which a central controller is networked with in-house energy consumers, energy generators and energy stores in order to provide the user with in-house energy via an interface and a data transmission system -Show profile and make recommendations for in-house / on-site energy saving and / or in-house / on-site energy generation and / or in-house / on-site energy storage. The content and teaching of this publication should be included in their entirety in this application.

Disadvantage:

The generated consumer profile and the retrievable information are only consumer-oriented and are used to control consumption, i.e. only show the consumer where and how a cost saving or a reimbursement benefit could be achieved. However, it is not possible to optimize the energy industry while taking into account all in-house systems. In addition, none of the known systems takes into account the stability of the in-house and / or external energy network in the event of strong fluctuations in the power of the in-house energy consumers, energy stores and / or energy producers, for example if the in-house energy producers fail or overproduce.

Problem:

The object of the present invention is therefore to create an energy supply system which ensures the stability of the in-house and external energy network in the event of failure, underproduction or overproduction. In addition, this energy supply system is intended to optimize the self-sufficiency of individual consumers and their overall energy costs.

Solution:

This object is achieved according to the invention with a smart home according to claim 1 and in particular with a smart home arrangement for use in an energy supply network of energy consumers and energy consumers of an energy supplier, which network has at least one common power network, a common gas network and a common information network (for real-time data transmission) and a hybrid power plant, this smart home arrangement for an in-house complementarity to optimize the efficiency and / or annual usage figures and / or annual performance factors and for a system complementarity to minimize energy costs and optimization the degree of self-sufficiency and energy complementarity to balance different energy sources, in particular electricity, gas, hot water, and an in-house energy management system with means for recording, calculation and visualization for the energy management moderation of the energy network eration of the current and / or annual degree of self-sufficiency, hereinafter also referred to as smart metering means, which energy management system is coupled via the common information network to a control system of the hybrid power plant, the common information network being a real-time data transmission network includes.

Definitions:

In the following, self-sufficiency means that all of the energy consumed in the smart home (electricity, gas, heat, etc.) is generated or manufactured independently with its own resources. Self-sufficient systems only use their own energy and are independent of imports. The degree of self-sufficiency is defined by the ratio of in-house production to total consumption. Consumers are intended to refer to energy consumers who use electricity and / or gas, i.e. have their own oil heating, heat pump and / or gas heating, etc.

Under prosumers are to be understood here as energy consumers who have in-house energy-generating systems, in particular those for electricity (PV system, wind power, etc.) and / or for gas generation (via electrolysis, methanation, pressure vessels, for fuel cells, vehicles , etc.) and supply parts of the self-generated energy to an electricity or gas network. In-house complementarity or in-house complementarity: prosumer self-sufficiency System complementarity: intelligent mix i.e. Optimized combination of house installations allows the simultaneous exchange of energy between prosumers / consumers Network complementarity: simultaneous balancing of energy supply and energy demand in the electricity network Energy complementarity: postponed balancing between different energy carriers 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 the prosumers is higher than the demand. For the prosumer with network storage: surplus electricity can be stored in the network and can be drawn back in electricity and / or gas with a delay. Increase in the self-consumption quota, i.e. promoting the degree of self-sufficiency in the smart home. Tariff optimization Consumption visualization Stable supply network Cost optimization, i.e. overproduction of electricity from summer can be used in winter, e.g. in the form of gas

Embodiment:

In the following, the invention will be explained in more detail on the basis of exemplary embodiments and with the aid of the figures. 1 shows a schematic representation of the energy complementarity according to the invention of a regional energy network system with several local smart home network systems; 2: a schematic representation of the in-house and system complementarity according to the invention in the case of a plurality of smart home configurations in a local smart home network system.

Character description:

Fig. 1 illustrates the principle of dynamic networking, which allows the individual consumers / prosumers and / or the local network systems to grow in line with market requirements. In addition, every single smart home has an in-house, system and energy complementarity. The local network systems are coupled to one another via a common energy network (electricity, gas, district heating) and a real-time data transmission line and connected to a hybrid power value. The moderation (network control) of the individual smart home and local network systems is carried out via regional energy data management.

The smart home network system shown as an example in Fig. 2 shows a plurality of possible in-house energy generation systems and energy loads, typically: - House entry with central network and system protection, including energy measurement (gas, electricity meter) and firewall; - Photovoltaics with energy measurement and feed-in management; - solar collector; Wind power; - HP (heat pump); - Power storage with energy metering and system switch; - WKK (thermal power coupling, heat generation, gas heating) with energy measurement and system switch; - Heat storage (with DHW) with energy measurement and system switching; - 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 management system, hereinafter also referred to as energy manager). Energy manager includes the determination of the final energy, useful energy, storage potential, self-generated energy, return delivery, self-consumption rate (degree of self-sufficiency) and optimizes the utilization of the in-house systems in such a way that the current, resp. Annual degree of utilization of all installed systems (in-house complementarity) to optimize the degree of self-sufficiency and thus to minimize energy costs. The current, resp. Annual self-sufficiency in% is determined from self-consumption / total consumption, in particular including gas. In principle, the on-site generated energy (electricity, gas, etc.) should mainly be used for personal use, since the savings made by electricity not drawn from the supply network usually exceed the remuneration for the feed-in.

The coupling of the in-house energy manager with the energy data manager of the control system allows the network load to be moderated by optimizing the interaction between the consumer / prosumer and the energy supplier. In particular, this networking enables the necessary balancing energy to be made available on time 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 supplier if the energy supply of the prosumers is higher than the demand. For all prosumers, the surplus electricity is stored in the network and can be obtained in the form of electricity or gas with a delay.
