<P>PROBLEM TO BE SOLVED: To stabilize a power system when introducing a distributed power supply. <P>SOLUTION: In a distributed power supply demand adjusting system 1, a PCS4 as a master station and a large capacity battery B are located in each substation for power distribution, a relay station 3 is located in a transformer tr, and a slave station 2 is located in a customer house where a load L and a photovoltaic power generation device PV are provided. The slave station 2 generates power information from the customer load power P<SB POS="POST">LL</SB>and the like and transmits the information to the relay station 3. The relay station 3 receives the power information from the slave station 2 under the transformer tr, collects load power included in each item of the power information and transmits information of the collected load power to the PCS4. The PCS4 receives the load power information from the relay station 3 located in each transformer tr which is interconnected to a distribution line, collects the load power included in each item of the load power information, transmits information of the collected load power to another PCS4, while receiving the load power information from another PCS4. Then, the PSC4 accommodates deficient power for the load L with another PSC4 and issues an instruction that the load L to the overloaded slave station 2 is suppressed or interrupted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
