Embodiment Construction

[0051] Next, modes for implementing the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings accordingly.

[0052] figure 1 It is a functional block diagram showing a configuration example of the electric power supply and demand operation management system 4 of this embodiment.

[0053] like figure 1 As shown, the power supply and demand operation management system 4 of this embodiment includes: a power management device 1 installed on the public utility company side to provide power to each user; The user's power utilization device (power utilization device) 2 on the other side.

[0054] The user power operating device 2 on the user side includes electrical equipment 21 , user EMS (Energy Management System: Energy Management System) 22 , supply and demand coordination operation client 23 , PC (Personal Computer: Personal Computer) 24 , and a test meter terminal device 25 .

[0055] The electric device 21 is...

Abstract

The present invention provides a power demand-supply management server and a power demand-supply management system. The power demand-supply management server (10) obtains information that defines restriction specifics regarding comfort and electricity charges from a customer's power operating device (2). An individual customer control optimization unit of the power demand-supply management server (10) then calculates electric equipment control specifics to minimize cost evaluation value based on the simulation result for a cost evaluation value, which is an index for evaluating comfort and excessive electricity charges, and transmits the same to the customer's power utilization device (2). An overall customer optimization unit of the power demand-supply management server (10) also calculates the optimal metered electricity unit price which assures a planned demand-restriction amount required for the power system overall based on daily load curves for each customer.

Description

technical field [0001] The invention relates to a power supply and demand operation management server and a power supply and demand operation management system. Background technique [0002] The greatest concern when performing operational control of the power system is insufficient supply capacity. In this case, measures to temporarily suppress the user's power consumption may be taken. [0003] For example, as one of the methods, a public utility company in California, USA provides an example of a program called "demand response" to users. There are several types of this program, for example, a program called Critical Peak Pricing (CPP: Peak Power Price) has the following functions. [0004] That is, participants who join the program sign a contract with the utility company in advance. Participants accept the preferential treatment rate that applies the electricity billing unit price set at a low price. The utility company decides on a daily basis whether or not to use...
